It bothers me (slightly,) when people recommend that I watch a music video that they like, while we're chatting.

I mean, once-in-a-while, it is okay, but there are some people out there that send out links at least once per chat.

Usually, while I am chatting, I am already running my own sort of secondary entertainment.

Of course, I am guilty of this too.  But I try to keep my suggestions to a minimum.
