Welcome to the Dope, brian.
There is…not a lot of love for Facebook-style functionality around here. Go take a look at the currently-ongoing “we’ve added share buttons” thread in this forum if you want a taste of it.
And yeah, nothing wrong with just posting “This made me laugh.” Personally I always appreciate hearing that someone liked one of my posts or whatever. (Because at heart I’m a narcissist with low self-esteem, but let’s not quibble.)
