I sure hope so. I'm already getting sick of the "Show HN: Only Works In Chrome (only works in dev version of Chrome)" links that were starting to show up.
As a firefox user i agree, it's a little bit annoying, but don't think this fragmentation will have any effect on it.
Problem is that most developers use chrome, and chrome have more cool stuff, so they wouldn't care about safari just like they don't care about other browsers now.
