>>Wrong. It is a tool that I find invaluable, as, I'm sure, do many others who have me on their filter. You may not like being Twitted, but the person doing the twitting likes it very much.

>I understand this position, but we're all professionals here. Why do we need to hurt people by doing so? There are technical problems we're discussing and if you don't like someone, you can skip his/her messages, but there is no need, IMO, to put that person in the twit. It makes the conversation very strange, when one person may try to offer suggestions and the other person would not even see them. Waste of time for the one writing. Waste of mental energy. Waste of lots of other good things.

Not a waste of time because others will read the messages and possibly get something from them. It's not about hurting people, it's about removing them from your short-range sight.

>Besides, you don't know how the other person may handle this thing. He/she can become so obessed with that that it may create some problems outside the forum.

No different than disagreeing with someone. I'm not responsible for how someone reacts or for their thin skin.
