Thanks a lot for your post e1ven. Yours is actually constructive and makes sense, a far cry from the usual "RubyGems sucks and I won't tell you why, but if you use it then you're an idiot"-kind of FUD. I've replied to your points at http://stakeventures.com/articles/2008/12/04/rubygem-is-from... (search for "Actually, the Hackernews comments were surprisingly constructive"; the post might now show up yet because it's still in the moderation queue)

A lot of your criticisms have already been addressed in the latest RubyGems version.
