Unfortunately, it seems to clash loudly with one of the Ruby or Rails plugins I use (most likely rails.vim, and its RAbbrevs). Being admittedly fairly ignorant when it comes to vimscript, as well as being impatient, I removed snipMate for now. If you have a quick solution for such woes, I'd love to try it.

I'd be willing to maintain a fork on GitHub that avoids clashing with rails.vim (or whatever the issue is), if we can figure it out. Maybe I'll actually properly learn vimscript as a result.
