tools: Chandler vs. Backpack

I've started testing out BackPack and its collaborative WriteBoards, and finding a few awkwardnesses ... will eventually be writing up a 'review' with my results. I am also going to compare it to Chandler before I make a paid-upgrade decision or invest substantial data-time in BackPack. At first glance, Chandler's pluses are that (1) it's free (elemental BackPack is too, but I hit two of the limits of free accounts in less than a day), and (2) it seems to have some nicer to-do list management features (like triage and ticklers). BackPack may be stronger in live document co-authoring, though (the WriteBoards). Stay tuned!
