It wouldn't bother me too much if, after a series of comments on my articles someone asked me ONCE to follow them. But I see the point.
Let me ask you, is it in bad taste in your opinion, for example, to read a post on something like, a movie review or video, and then to ask someone to take a look at a similar review or post that you've made?
I wouldn't do it in an oping comment, no.
Think of it as though you were talking to a real person. :)
