I hope not. While I don't hate Facebook and use it regularly, I don't think they need to be in control of a browser. I really like Opera (if IE9 wasn't as good as it is, I'd still be using Opera as my primary browser), and it is currently my backup browser. Considering I hate using both Firefox and Chrome, I rather hope Opera doesn't go down the gutter; its nice having a choice between IE and Opera, whichever is better for me at the time.
Right on, Scorpio!
Only different thing I would've said is that I do hate Facebook!!
