You rock! :)
Have you talked to other folks whom have reached there friend limit, to see what they do? It seems like this is one of those things that's like.. a very kinda sensitive place.. I mean.. so easy to make someone feel they don't matter.. One of the things I REALLY admire about you is your ability to make people feel like they matter.. like they're not just another number... Seems like its sooo core to your personal brand that it's potentially more of a sensitive thing for you then it would be for the next guy...
Also.. if I felt like I was just a number.. or if someone made me feel that way.. if there content is still important to me I'll come back to them.. but while I'm smarting from it.. I'd probably be tuned out for a bit.. so I might not get this message.. So I wonder how to approach this group.. if you might want to take a step beyond this.. I don't know.. I know I qualify as "a highly sensitive person" so maybe that next step stuff is just me, I don't know..
And Chris, you don't feel anyone is worthy enough on Posterous to subscribe too?
