In general, I like it, but many newbies aren't set up with sats and a lightning wallet yet.  That makes them unable to pay to follow and makes them leave.  Until it is a little easier to setup a wallet and zap really easily, that would just drive people away.

The other problem is what happens when bitcoin sky rockets and a sat is real money?  We don't want to force something that causes problems later.  I suppose if it was optional, it might be OK.

That being said, I'd definitely be willing to pay a sat to follow someone.
