Well, I just got invited for Google FriendConnect! Let me tell you a bit about FriendConnect.
With FriendConnect you can easily join Ariejan.net. See of it as a pool of Ariejan.net visitors or fans if you like.
Once you’ve joined up (with your google account, for example) you’ll be able to interact more closely with Ariejan.net. In the case of Ariejan.net you can share your thoughts with other Ariejan.net visitors. Just vent your frustration about Linux or let others know what Rails project you’re working on.
Another benefit for you is that you can see what sites other people have signed up for as well. This way you’ll be able to get a list of sites that Ariejan.net visitors like as well. You might compare it with Amazon’s “other people also bought..” feature.
The big benefit for me is that’s it’s nice to see the list of fans/visitors growing. After all, that’s what I’m keeping a blog for after all.
In the future I’ll be able to add other widgets to Ariejan.net. This allows for other features to appear on Ariejan.net and a better over-all user experience.
