Have you guys heard about the
Archive of Our Own, an archive created by the
Organization For Transformative Works? I've created an account and
archived 3 AM there, plus I'm starting to
bookmark fic that I like.
It looks like an awesome archive, both for posting fics and browsing. It's easy to search by fandom, pairing or tags, and there is a filter so you can really get specific with your searches. Commenting is easy, and they even have a bookmark/rec feature that allows you to bookmark your favorite fics and search for bookmarked/recced fic within a given fandom. That part looks really cool, sort of like delicious, but with just fic and all in one place.
Also, they've come up with a system to connect tags that are related, so when I search for 'Kirk/Spock/Uhura' fic the archive also shows me fics tagged with 'Kirk/Uhura/Spock' and Uhura/Kirk/Spock' and 'Jim/Nyota/Spock', and so on. I think that's awesome, because one of the downsides of delicious is that if you didn't search for an exact tag you wouldn't find the bookmark. So in order to find all available fic you had to search all possible tags, and that's just kind of annoying.
So the Archive looks awesome, but there aren't a whole lot of Trek fics there yet. Come and post more, cause this fandom is huge and deserves to have a ton of fics posted!
*NOTE: the site is still in Beta, so that means they are still working out the kinks and bugs. Things may not always work correctly, and the only way to figure out what works and what doesn't is to do a trial. By signing up now you are agreeing to be a Beta Tester for the site, so please
pass along any problems or feedback to Support! Also, there is a waiting list for new account creation, but hopefully you won't have to wait long to get an invite.
ETA: There are now a few good write-ups about the tagging system the AO3 is using:
Tags (Wuzzles) Explained by Zvi and
OTW's Archive of Our Own, and Tag Wrangling by damned_colonial. Plus samvara is keeping a list of bookmarks on
AO3 tips and meta. A lot of work is going into making tags easy and simple to use, flexible enough to keep every one happy, yet complex enough to really build a fannish infrasturcture that resembles the way we work. For example, like Zvi said: "also, they realised that they needed to make a way for a wuzzle to be a subset of another wuzzle, like Backstreet Boys and *NSYNC need to be sub-wuzzles of Popslash, so that if you click on the Popslash wuzzle you get both of those, but if you click on *NSYNC, you don't get Backstreet but the code for this was tricksy, so that’s not built yet." It's not all complete and perfect yet, but they have grand ideas and I have no doubt they will make them happen.
ETA 2: It's pretty easy to figure out how to post, but if you want help,
here is a pretty detailed set of instructions with pictures to guide you. They were written with Yuletide in mind, but everything besides posting to a collection should apply. Although, you can post to any of the many collections that have cropped up using the same instructions.
