Gr. Diigo, really?

Since Diigo seems determined to make their service a fandom-unfriendly place, I have decided to cough up the money for a Pinboard account. I don't like the thing about the sign-up fee, but I'm willing to stomach it once. The import seems to have gone on alright: check it out

I am worried, though, about what's going to happen to all the organizing and thought that went into organizing the tagging and referencing of comment fic challenges. The Dresden Kink Meme, previous organized on Delicious, rocked my world and showed a whole lot of anon!talent- what's fandom going to do for this kind of crossreferencing in the future? Separate Pinboard accounts for each challenge seem like it would get more costly than anyone would want to admit.
