Google+ what?

I just made it into Google+, considered to be the Facebook rival. Wow!

So far, it has been a very protected system - by invitation only. Still not available in Google Apps and for Google Apps accounts. Quite frustrating on that front. I was lucky to get an invitation from a colleague.

But, is it a good thing to keep it so protected and keep potential users longing for the system? I wonder if that's a productive way of introducing a system for which success will depend on numbers at the end of the day. Google should learn from the past. Its search engine became popular and dominant simply because it was easily accessible to everyone - no restrictions. I feel that the same principle should apply to a social networking system.

I'll try it out for a couple of days and see whether it was worth the wait and convincing enough to switch from good ole FaceB.
