I, for one, am a long-time NNW user who was lobbying for Google reader integration. I didn't like how slow NewsGator was to fetch new items from feeds. I mean several of my feeds, even very popular ones like Daring Fireball, were a day late. That's not acceptable for someone who sees the world through RSS. I wanted it to sync with Google Reader because I preferred their mobile implementation over the NNW mobile app. Plus, many of my friends use GR as their reader, and there are a number of useful social features I'd lime to see come to NNW. I didn't have a problem using their beta, I've always used their betas, but I did have a very bad sync at first. But I had backups, as forewarned, and recovered quickly. And of course, having 10.5 was not an issues for me :-)
