The main reason I don't want Google+ to succeed is because it would not only mean having to re-add all my old friends (and this would take months if not years given that so many people have taken so long to get Facebook as it is) but it would also mean having to re-add photos, hope that my friends also re-add photos that I liked, and then re-tag all those photos. And then there are the lost messages between me and my friends that would end up left behind. Amongst other things.

The people who constantly switch from social network site to social network site must be the same people who change emails all the time. All they do is make things difficult for everyone else when it comes to keeping in touch with them. Which is ironic, because that's actually what social networking sites are all about.

Facebook won't die "because MySpace was popular and it died." MySpace had horrific problems, mostly surrounding load times and the severe customisation that was allowed to users that ended up causing untold amounts of errors and subsequent further problems with loadtimes. MySpace basically cocked up. Facebook hasn't really done that yet, so I'm holding out hope that it will pull ahead at the end of this. Not because I think Facebook is amazing, but because the number one thing I want in a social networking site is consistency... basically, to not have to change to another social networking site just to keep up with my friends all the time.
