hasn't it failed? the relevance of google + is kind of lacking, trying to fluff up numbers by forcing people to create dormant google+ accounts is total bs.
first they did this with youtube...and now this. they are getting a bit out of touch as they get older. remember why we liked google in the first place, they were the one search engine that wasn't forcing shit down your throat, they kept it simple, doing only what you wanted, they seem to have lost their way.
I would agree it hasn't been very successful yet. But at the same time I'd say its too early to say it failed. I'm sure there were people saying the same thing about Android (hell they still are).
I'd also agree numbers are meaningless, in fact, that's half my argument. Why are people gauging success solely on that? I bet + has as many legitimate users as a lot of other social sites that have been going for years. And there's plenty of ways that Google can grow it (including interjecting it into search results).
This is really far too much analysis for this anyway, I'm in no way saying its been a rousing success. I'm just saying its way too early to declare + a failure.
I'm pretty indifferent to this. I tried searching for several things to see what the OP was even talking about and it didn't do it until I searched for Facebook incidentally (which brought up Zuckerberg and then I think two Google people).
If it in any way hurt their search (i.e. fullscreen pop-up, caused search to take longer, etc) then I could understand it, but I'm not seeing a big issue to be honest. I don't entirely agree about Google for simplicity, as plenty of times its specifically for maps, image search, and other features that I use search, so simplicity is not really the main motivation for me. Often its the mix (i.e. I search for a product and want to see the shopping results to compare prices as well as sites with reviews, etc).
