It seems we're going to lose Google Friends Connect for non-Blogger blogs at the end of the month, and then altogether in due course. This is a great pity - I really like the dashboard and the activity centre that it provides.
Have a look at this link from Kate Palmer (if it works): Ah Nuts - thanks Google :O(
The important thing is to remember who your connections are, particularly if they are using WordPress or TypePad. I gather that Mr Linky has put up an application called Linky Connect which will be an adequate substitute. Might even be better so I'll be looking into that.
