In response to the grouping of contacts problem – we did have some code for that, but it’s not that good so I am going to work on some better code for that over the next few days.

In regards to the other sites you mentioned:
friendfeed: As you point out, if you have a lot of friends that don’t use friendfeed (i.e. they are not early adopters but you are) then it’s at best cumbersome and at worst useless (i.e. most of your friends are on facebook, which they don’t support well).

Ziki: I had a look at it, but I can’t see how it helps you keep track of what your friends are doing and they seem to have changed direction since the coverage they got before.

Profilactic: I’ve just tried to use profilactic though it doesn’t seem to have moved on much in the last 18 months and their facebook support doesn’t really do anything (just gives a link to your profile – no updates from friends)

We would like to hear further details of any problems and any suggestions you had so we can make the site better, either in our discussion group, bug tracker or via email. Details here:
