After 48 hours or so of hardcore use, today I decided that I hate Rockmelt.
Used as your primary browser it gets insanely slow and data-heavy and the lag is insufferable.
And because you can't organically update Twitter/Facebook from the right-hand pane, having them ever on the periphery doesn't actually stop you from having to go to those pages. All it really does is make you a compulsive newsfeed update-checker, which is something you thankfully forget about doing from time to time when you're not constantly gazing at those icons.
Back on Chrome again. Will I return to Rockmelt someday, to visit? Probably, but that I'm saying "probably" probably means no. I'll keep it on the dock awhile though, just in case.
This concludes my review.
UPDATE, 13 Nov: A few commenters actually pointed out to me how I can update my Facebook and Twitter statuses from Rockmelt.
It's on the left!
There's also some kind of "smart" RSS suggestions feature that passes you fresh sites based on your interests (StumbleUpon-esque?). I haven't yet figured out how that works though.
Thanks, guys. Maybe I'll give this another go (but that laggage, man... find a way to work it out!).
