You're kind of like that ice-cream truck that goes through neighborhoods with lots of kids around and never stops.
I rarely trade options but I remember reading in Futures Mag an article about spreads and executions which advised to cancel your new offer when a MM join in, wait until she cancels too and then reroute to this MM. Chances are she won't raise her bid or lower her offer because anyway you posted on her exchange.
And the *answer* to your question is that there were always "likes" but the likes went to the post (and stopped), not to the poster (to accumulate into an ego-inflating super-balloon wrapped around your head). So, the posts you read were old old old. Hence, no "likes" to the posters. (That's my story, and by cracky, I'm a'stickin' to it.)
Jeez, speedo! You've been here longer than me! And now I observe you've got 773 Likes!!! WOWzer! So, like, you've been garnering them since 2003?!?!? I never posted much before this past Christmas/NewYears -- had ~80 posts before that. And no likes. I just never thought about it. Now, with a nearly 45% Like Ratio, I can barely fit through doors with my head so big. But JEEEZ! 773/1043..... wowww-wwwwwww. Well, color me (truly) impressed.
