Skype is too slow and crash-prone for my liking, so I'd like to use an alternative that won't require my current contacts to set up new accounts so I can stay in touch with them. Someone recommend Trillian to me once, but all it did was link to my existing Skype account so there wasn't much point - I didn't have any others for it to helpfully consolidate together. As for Google's alternative, Christ alone knows what they're doing and he doesn't talk to me any more.
