just in case anybody wanted other suggestions
tumblr is good since it's got a really straightforward posting system and it's easy to keep things organized if you remember to tag them. it's free and there are a lot of browser addons for it to improve the site's system. it's my personal choice for things that aren't quite polished enough to go elsewhere. other blogging-type options are
xanga,
livejournal,
blogspot,
deadjournal,
wordpress, and of course the aforementioned
blogger. all of these websites are free to use.
there's also your typical art/photo album sites, like
deviantart,
sheezy,
furaffinity (if you're ok with furries that is),
elfwood,
flickr,
picasaweb and others.
if you want to post webcomics, there are sites for that too. such as
comicfury,
smackjeeves,
webcomichosting,
comicgenesis, and
comicdish.
i have yet to find anything specifically for hosting literature outside of
fanfiction.net and it's adults-only counterpart but i'm pretty sure that's not what you're looking for.
as far as hosting music, there aren't quite as many options for this sort of thing but the best ones are
soundcloud and
bandcamp if you're looking to sell it.
and if none of this suits you there's always the option of putting everything into
dropbox and posting about it here. dropbox is a web hosting resource that operates from your desktop, i swear by it.
