Thanks for the reply! I’ve been playing with Gqueues. It’s interesting, and I’m planning a GTD in post with it at some point in the near future. I’m pretty invested in Producteev, though. I can’t wait for an iPad app to finally hit, but I’ve been doing well with the iPhone app and web app thus far. I’ve never found it sluggish, myself, at least not in any way that I’ve noticed — but you could have a ton more tasks than me.

There is an Android app around the corner, by the by. ;)

Pinboard is new to me — I’m going to check that one out!
