Kinda depends on what you are doing the project for and what aims you have for it - if it's just for kicks then I'm sure something similar has been at least attempted before, but if you are writing a paper, say, then previous attempts might be worth looking into first.
Your aim/goal is a little indecisive, it's hard to say what you are wanting to create - do you mean that you want to create a website that has all those things incorporated into it? If so, you have to ask whether there is any demand for that sort of thing, as each part has already been done and you have to find out whether there is any need for those things to be brought together (networking sites such as Facebook sound kind of similar to the collection of things that you want to do, but people can share them amongst themselves and socialise at the same time).
If you just want to stick all of those concepts onto a single website, then it's something that has been done, and has in most cases failed due to it being too random to attract a certain audience. There are thousands of sites out there where the author has stuck on lots of different little glittery objects that they were attracted to, leading to one giant mess of a magpie nest - too many things to make sense of, each too shallowly looked into to attract a person wanting that section.
It's like marketing, you need a product, you need to work on that product properly and make it perfect, you can't get distracted by little bits and pieces along the way. If people want something on the net, they will look for that thing alone when they need it, and you need to stand out from all the other sites.
Having that one thing in a giant clump of other things will put people off, confuse them, and lead them to think that your offering is a tiny glossed over section of a larger whole, the rest of which they are not interested in and don't want to trawl through to get to what they want to see.
When the internet first started it was a place to create anything you wanted, with anything you want to show - it still is, but the net is so large now that your offering will be completely ignored if it doesn't stand out or offer what the visitor wants. The internet is much more commercial and business-like. You have to offer something that no-one else is, and it has to be something that you can do better than anyone else out there so far. And people have to want it. A page full of trinkets that are there solely because you like them won't survive out here anymore.
If you want to create a page for it's own sake, to see if you can and to show your friends things you find interesting, then there is nothing stopping you - just don't expect a lot of visitors.
Sorry for banging on, but it's really not clear what you want to do, why you want to do it, whether it's needed, and what it's final form might be. Figure these things out and you'll be halfway there.
