>I want the person to know I actually looked at the post and liked it.

And you thinking leaving a comment of "Nice pic" shows that? Do you have any idea how simple it would be to make a bot that posts such comments? Now, given that a user is posting the same crappy comment on multiple articles, the chances of them actually liking your article are slim to none. It's more likely they're running a bot to post that shit for them and are not even aware of the article you posted, never mind actually liking it. They're simply kissing your arse in the hopes that you upvote them.

As an author, I couldn't give a flying fuck about "appreciative comments" which simply waste my time. I'm not a 5 year old that needs a pat on the head and a gold star for being a good little boy. I like the comments that disagree with what I have to say and provide reasoned arguments as to why they disagree. I love heated debate and can't stand people trying to kiss my arse.

@choogirl - Nothing wrong with simple comments.  
It's just annoying when you check the history and it's a copy / paste of the same comment over and over within a very short space of time.  

You can clearly see the difference and I would never penalise someone for saying Great Post or just a word or two.

@stormuk69 and @marcusorlyius Its good that we have to have the meaningful comment or the comment which brings the value to the post. But sometimes you just want to say wow looking at the pictures and nothing else. 

I know we have a lot of bots out here which by doing spammy comments increasing its value but that doesn't mean that the real user will be penalised just by writing one or two words as a comment.
