Sporks are so cool! They are a spoon AND a fork! But they never replaced actual spoons and forks. Because while sporks are an improvement over the old design, they just weren't better enough for people to bother to switch.
People moved from myspace to facebook because myspace got too slow and spammy. Also facebook was "cool" because initially only kids in prestigious colleges could get an account.
Google+ needs either some killer feature that is so much better than facebook that it compels people to switch (if they have one they haven't shown it yet) or facebook needs to become unusable in the same way myspace became unusable.
"Instant Upload" really depicts what I dislike most about Google's software at the moment. I already have two separate sync mechanisms on my phone from Google (contacts and apps), now they're making a third. Why can't they just make one simple sync thing?
It feels like they're just launching a smattering of separate vaguely "social" 20% projects at us, when really they should have taken the best bits and integrated them into existing applications. Huddle, for example - doesn't Google Talk already have this functionality?
Circles is where I think social is going to be heading, but being first doesn't mean being best. Facebook has been headed towards this sort of thing for a while now, and once they have this feature why would anyone use Google Circles?
