That may make Google a bit more attractive to many users, but if you’re looking for online privacy, Google FriendConnect will likely be a less attractive application than Facebook Connect. With Facebook Connect you’ll still be able to tap into the same privacy features that Facebook has built into its community. But Google FriendConnect, being that it will be compatible with several networking sites, can’t promise that level of privacy. And some people are a little jittery about how much information they want Google knowing about them, so that’s one concern.
Both Google FriendConnect and Facebook Connect will allow you to turn your local website into a community portal. That could mean more traffic for you and a way to ensure that you can charge more for advertising dollars.
