As a newcomer I most definitely must have given karma in the wrong places: one reads and reads on in a thread and then the impulse strikes you: XYZ deserves karma right then and there in that particular post, may be not that relevant to the whole of the idea or the advice or whatever.
I also gave karma without commenting, thinking most people did not want to read more messages than they have to.
Being new means also one reads many older posts, the poster might have forgotten he/she ever thought that thought!
I think

the solution would be that all of you karma and comment lovers/haters etc. add an abbreviation to your pseudo, something like KCL,KnoCL or KCH would do the trick. Some of those might look cool too.
Have a good weekend all,
