Quicksilver is dead?? I still use it every day. Where did people go? :-/
Jitkoff works at Google and went on to produce QS "clones" called Google Desktop & Google Quick Search Box: http://googlemac.blogspot.com/2009/06/introducing-google-qui...
I'm still using the original non-opensource QS here with no problems (well at least no probs on Tiger!).
I never even notice the crashes any more, and when it starts acting funny I can Cmd+Q it and it will be freshly restarted in a few seconds.

In all seriousness, though, I can imagine the irritation that would be caused by crashes. I've just never experienced them, and I've been on the Quicksilver train since 10.4.1 or so.(I'm a ⌃Space guy myself)
