Earlier quoted context omitted.
I've heard this argument (mostly from Googlers) before. I don't buy it though, as I occasionally (rarely now) see friends post things and get zero comments. The same comments will get tons of comments on Facebook. This thing has largely failed outside of tech circles and twitter style (celebrity) newsfeeds at the moment. Hopefully that will change, as I find it superior to Facebook in virtually every way.
I'm curious, what are all the ways in which you find it superior? I agree that circles are better than Facebook friend lists, but G+ seems to lack some features that others find essential on Facebook, like event creation. I've heard a lot of people say that's the biggest reason they have a Facebook account. Also, there's no direct messaging system, at least that I'm aware of. FB messaging has basically replaced email…
I know a lot of people use Facebook for messaging, but I would honestly prefer that they just email. I don't really see the advantage of a non-email email over just using email. Google+ email and chat integration are just fine.
You don't have to manually put people into their own circles. If you share something, just start typing their name (instead of a circle name) and it will let you share with individuals instead of circles. It works the same way otherwise.
I find the slowness surprising, actually. Whenever I've used + it always seems either the same or faster than Facebook. Perhaps this has to do with specific network environments or something? I have noticed that it takes a while for updates to propagate (caching, I guess) across to other users. That part is a little annoying at times.
