I have seen the number of visitors on my site drop quite a bit. I’m not sure that I’m the only one how is seeing it. I guess that it is because Wave is not as novel any more and people how want access an ready has access. They can therefore create their own opinion about how it should work and how they can use Wave.
There as also be fewer announcements of software for the Wave. It could be because we was near christmas and it was not time for any news, but there could also be reasons like the users are not ready yet.
We saw last year that 12sprints(a SAP project) was released, which in some aspects looks like Google Wave but more structured. An Novell which created a property Wave server them self and then found they could support Wave instead and get more traction. I think there will be more products that lean towards Wave as a way to appeal to a larger community. The different softwares will make the usage more difficult to figure out for users and to select the correct tool for them.
I guess that it is the early adopters using Wave now and they are introducing their friends to Wave. When I was introduced to 12sprints the idea was to figure out how you will use it your self and then add your friends. With Wave it is a bit different, on waveyou just add you friends and then figure how you will use it. That mean you get a lot of different options on how wave can be implement. I have many different ways I’m using Google Wave and with different parties. There are many different use cases with Wave.
A problem with Google Wave is that it is seldom you notice any difference in the interface, and many of the changes are small to fix some bugs. Ie the Robot api has not been changed since 16 september, even there are some improvement that would be nice to implement.
