1st point this is actually the 1st time I've seen the Google + comment box in use. Interesting.
Secondly I'd have to agree, hasn't lived up to the hype, if anything it's made the SERPs worse, what I've seen is a lot of mid level guys be crushed, the big got bigger and there's now more garbage in the SERPs.
And whilst the mid level older "filler" sites aren't great for the user they're certainly better than some of the things ranking in their place.
Burn sites on brand terms are making me some good money at the moment so I probably shouldn't complain too much ;)
