Ubiquity belongs to a very large class of software, that which I find deeply interesting and compelling—yet is so disruptive, requiring enough memorization and adjustment of my habits, that I never adopt it, and always set it down or let it lie dormant after a couple minutes of playing. It's not that I come to any verdict and decide not to use it; but there's such a huge gap between, "This will be very useful! Let's stick it in the toolbox!" and "This is a great tool that I'm comfortable and happy using frequently!". Most of that gap is occupied by many individual, "I know! I'll use Ubiquity. Good thing I was aware of what kinds of problems it would be good for, remembered that it would be appropriate to use here, and remembered what in fact to do."s.<p>Last time I picked it up Ubiquity did nothing to help me traverse that gap. But here I am downloading it again at .5 so we'll see if things will be different.
