i dislike launchpad
I dislike launchpad. So much so, that when I am using a piece of software, and I discover a bug, and the only way to submit said bug is to use launchpad, I generally just give up on submitting it. The barrier for entry/use is too high.
In a similar vein, if I run across a project using bazaar (often tied to projects on launchpad), I tend to be less interested in the source.
Maybe I have become a “tool snob”. Either that or it isn’t just me, and launchpad and bazaar really are as awful for other people as they seem to be to me.
