I know big bro. Some people just don't know how to say things, some fit into talking, some fit into writing, some just utterly speechless, some just don't want to hurt anyone, some just busy with real life, etc. I'd be a good idea to consider and that'd be making this forum more interesting with such feature. Because there are so many silent readers out there…
I have another proposal; instead thumb up icon, how about heart thing like what I saw in Tumblr
I myself don’t mind tho because I do what I love, so it’s alright for me. But, dunno about others. But, yea! I have no rights for that. Just a suggestion… It’d add another value to this forum. But, need to consider about two-edged sword effect too.
