If you don’t currently have a Jaiku account then you may be out of luck because in the notification email sent out by Jaiku last night they said:
In order to focus on innovation instead of scaling, we have decided to close new user sign-ups for now. But fear not! All our Jaiku services will stay running the way you are used to and you will continue to be able to invite your friends to Jaiku.
I’m not sure what happens to people who are invited in this period, do they go into a holding pattern, or are they left in but the amount of invites is limited. The faq is no help there.
This is great play by Google who are demonstrating that they have their finger on the pulse. I can’t wait to see what other announcements they are going to make in this space – Robert Scoble is hinting at big news in the Orkut arena in early November.
Jyri Engstrom, Jaiku’s founder gave a great talk at Reboot and I tried to get him to come to speak at the it@cork conference this November. Unfortunately he was busy (now I can see why!). Maybe next year Jyri!
