Is recommending a post like 'liking' something on Facebook? Does this have some effect on the position of the post? It's hard to understand how it could without messing up the sequence of ideas on a thread — or does it affect the position of the whole thread? I am not understanding the whole 'recommending' thing - also, what is this 'grey posts' phenomenon people keep mentioning? All the posts look the same color to me.

Easily confused,
