Yes.  I think it's annoying.
If you consider yourself serious enough to need a logo, then I hope you have the creative intuition and skill set to make one yourself.
...if not, then you must be serious enough to go see a professional designer or personally contact one, not just throw it out there and see what you get.  Making logos is a personal thing, and you should have an idea in mind.
...so yes, its annoying and should stop.  I've been biting my tongue until now.
