This question already has an answer here:
Recently, a person commented on my answer to a Literature question...
aroth: "...at least, according to Wikipedia" - Famous last words.
...and received at least 2 upvotes (possibly even 3). However, that comment then get moved over to a chatroom, and aroth's current comment has 0 stars. That doesn't make much sense. When it was just a normal comment, aroth had received upvotes and stars in Chat seems very similar to upvotes for comments. There's probably a really good reason for this process, so I'm wondering why this process exists.
