Of course, I may post to judge the quality of an idea, that's what discussion means. Shambles, you may think the best way to discuss is not to respond or only to respond nonsense but I don't think so. This particualr idea is in my eyes at best useless.

Discuss the subject by all means Wolfgang - this is a discussion forum.

But a post containing only a judgement of a thread's worth (as useless for example) or a post containing only a judgement of the poster's worth (as useless for example) - is not discussion. You have taken the time and trouble to post only that you judge something or someone to be useless ( for example) - so what? Will any other poster be interested in reading only this judgement?

If you were an important German, like the Pope they might - but are you the Pope?

Online - all posts containing only such judgements do, is to ensure that there will be a response in kind - as such personal judgements tend to be taken personally.

And posting to judge a thread's subject (as useless for example) - but still going on to discuss the subject - is an attempt to have it both ways and will make the judgement of even less interest to any reader.

If you do judge a thread or a poster to be useless - the very best judgement is not to post - but to ignore both it and them. For the thread will then quickly to be seen to die through lack of interest.

You may not then judge the poster's next thread to be so useless.
