I'm starting to get really tired of other people coming along and doing the exact same thing I was doing, but for some reason they always seem to get more interest and help than I ever do.

And then being asked to join them.

I know it's kind of petty but seriously, I was here first. Why don't you come help me instead?

@alahmnat drives me crazy when that happens. and then they get all the credit for the idea while you get a "thanks for your help!" acknowledgment in the launch announcement.
@alahmnat I can see why that would be infuriating.
