Once-Upon-A-Time, to 'get photo's 'out there', that's exactly what you did; you enthralled your family for a few moments at the dinner table with a packet of prints that fell through the letter-box; you took them to work and handed them round in the canteen, you took them down the pub. You might have put them in an album, and you might have dragged it off the shelf when visitors came around, and if you were really serious you might have got a projector out and bored your dinner companions to tears with a slide show of your hiking holiday looking at 20th century telegraph poles or whatever.....
Point IS, that you have muddles a few objectives here and are looking through the wrong end of the telescope.
The whole point of a picture is to be looked at. If no-one looks it has no reason to be... so starting there, before you even look at the camera, let alone decide where to go, or what to take pictures of.... KNOW YOUR AUDIENCE..... this fundamental will guide pretty much all else.
Who, is your audience? Friends/family, chap at work, bloke down the pub, or maybe, and top answer, 'only you'.
Why will that audience look at your photo? Why do you want them to look, and more importantly why will they want to look at it?
I have little to no interest what-so-ever in flowers, among other things. Mother is not just an avid gardener, but a horticultural lecturer. Granny's hobby was visiting public gardens, and taking photo's of the flower beds.... I was subjected then to many many pictures of the dang things, and even explanations, usually in Latin by my mother, and my eyes glazed over.... I don't care how rare or exotic that plant might be, nor how the colours are strangulated in the petal or whatever... it's a FLOWER. I am not interested in the ones in my own garden, let alone some-one else's. They hold NO INTEREST for me, I do not want to look at them. Real ones or photo's. "Ah yes, but its a beautiful Photo!" or in my mother's case usually not, and I am looking 'cos I have been asked the question "Why didn't this come out?" Which is to get into this critique lark, and its worth noting, that I STILL have no bludy interest in looking at effin flowers! I am looking because I am moderately interested in photography, and err, yeah, it didn't come out, Mum, 'cos it was dark, try turning the lights on or using the flash.... but guess what.... I am still not interested in looking at, yup you guessed it... flowers!!! Now... there is a retort to this, "well I am not interested in your motorbikes... I still have to look at and trip over the dang things though!" But that's the tip of another rather large iceberg! Point is, I expect that my mum, 'may' be moderately interested in seeing a set of holiday snaps of my kids, playing on the beach. They are her Grand kids and she probably wasn't there to see them playing herself. Which brings me to the....
What, will they be interested in looking at? Which is a pretty BIG question you have to consider. Interests vary and have so many different levels.
I have a few thousand photo's on the web. A good chunk of them, and the ones most looked at are mostly of them motorbikes my mother don't much appreciate. Fine, I don't expect her to look at them. They were taken to illustrate things, like where to find the carburettor balancing port on an old Honda twin. Anyone wanting to balance the carburettors of an old Honda twin, probable wants to know this, and so has interest to look at the photo. Kerchunk.. there is my audience... and 'the photo' as an image in its own right is of little significance, folk that have interest in looking at it, probably are not going to think it any better because the colour saturation is just so, or I have nailed focus, or its just so sharp. All they will be bothered about is whether it shows this dang balancing port they were looking for, and provides enough context for them to help find the actual one, on their bike, they are looking for.
Most such photo's are hosted on , boto-phucket, and displayed on my own web-site where I have written a whole article around not just one, but a set of illustrations to tell anyone how to balance the carburettors on an old Honda twin..... and in a lot of cases the pictures come second to the words. Some are on farce-broke where, for friends/family I have created an album of my exploits, including the photo's of an old bike being restored, and just as likely outings I have had with it. Friends/Family may be moderately interested to see an old Honda twin come back to life in my back yard, or to see pictures of a bike rally it eventually went to. B-U-T, I do NOT expect folk to come back to me on forums or on e-mail critiquing these pictures!
Which brings us back to your original query to be honest.
Why do you want / think you need a 'web-presence'?
What do you hope to get for it? And more importantly....
What, are you offering your 'audience' for their taking the time to look?
If you want critique to help you take better photo's, well, this site is as good as any, and it has a built in picture host, you can upload pictures for folk to look at to. But.... beyond that, WHAT is the reason for your photo? WHO is its intended audience? And hint here; most photo's will only ever been looked at by and are only of interest only to the person that took them... in which case they don't need to be published for the world to look at; the flash card in your camera or your computers hard drive is probably good enough.
And... for becoming a better photographer, the most important person to please, is yourself, so you don't need show your picture to any-one else to decide whether it pleases you or not; and whether it could have been better or not, is pretty subjective, and again introspective, YOU are best p;laced to say whether you could have done a better job or not...... which begs not looking at your own work, but other peoples and asking how they did a better job or not... and then making lots of excuses for why your endeavours don't stack up, and to improve, going around this loop, of self critique and critiquing other works, and taking lots and lots of photos and trying to get to grips with things like composition and the exposure triangle, in between times,.
In short, you do NOT need a 'web-presence' and it's not really a solution to the problem you suggest you want it for.
