I put all my drabbles in a "series". This means that they do clutter up my list of works (suddenly, 30 100-word entries! /o\ ) and I sometimes think they'd have been better off as chapters of one WIP entry instead - posting new stuff would boot it to the top of the queue, I think. But that would make the pairings, ratings, etc. into a nonsensical soup....

If you put your drawbles as chapters in one work, I'm not sure whether clicking the "show all chapters on one page" might not be hard to load after X number of entries? You'd probably need several WIPs: Stargate Drawbles, X-Men Drawbles, etc.
