I think the problems with like counts that are publicly visible on your profile (and not just under the posts - [b]if it were JUST under the posts, I couldn't care less[/b]) is that [i]others[/i] will be judging you based on your ratings/number of followers/views/whatever. Sadly, I've quite often seen people assert that since someone is "less popular", they must be worse. 

It also encourages laziness and takes away from incentive for giving constructive input - upvoting is easier and quicker, but someone voting up my post gives me next to no useful information whatsoever. 
(Did they agree with what I said? Did they just find that it was well debated, even if they disagreed? Are they just the type to upvote almost everything they see or read? Did they upvote just because they remember me from somewhere? Are they one of my "followers"? That one fellow who was strangely fascinated with me some time back? What?) 
I'd rather they either didn't do anything at all or actually took the time to, y'know, type out a reply or send a PM. This is one feature that will most likely just generate an extra layer of visible favouritism where friends highlight friends, as it sadly very predominantly holds true almost everywhere - if not [i]everywhere[/i] - where likes that are reflected on user profiles exist.
