I pretty much respond if someone mentions me on anything. It doesn't happen much, but I shall rise to occasion if it does. Often times, it is just a "thanks" on a "Who's a GAG friend" question, but if it is someone tagging me to get into a debate, I'll respond.
The only time I don't respond is when they are just mentioning me as an example but not wanting really an opinion of mine. I don't want to interrupt someone's conversation so I just leave it alone.
I do as long as it is warrented. Obviously if its just a some one saying they agree then it doesn't warrent a response and sometime people don't want to let things go and just start repeating the same arguments so after responding to it twenty or more times I will just stop nothing new can be said. Oherwise yeah I usually respond back, it would be rude not too.
Not, necessarily. I respond under two situations, one is if I think I should explain my point to that person or if the person has asked my some question then I do respond otherwise I don't always respond to someone who @mentions me.
depends. sometimes i get mentioned for the most ridiculous, rude, or creepy things. other times u kind of dont really need to. like when someone says 'ok' in a conversation, u kind of don't respond, u know? similar idea.
most of the time it's fine though and i do respond.
