ROTFL.

No, fans can see you and respond, but you don't see their original plurks. Generally you will friend, not fan, most ppl.

spies..

Good way of looking at it!

Might have to do away with my spies

I'm with Jaime on this one. Might have to do away with fans.

Well I fan some of the PlurkDevelopers. They don't want to see much of what I plurk, but don't mind when I reply in their plurks.

So fanning has its function.
