This question already has an answer here:  You require a
reputation of 50 to leave comments on others' questions/answers,
the FAQ simply states this as a fact but does not explain it.
I'm a new user and I have identified this as an issue very
quickly through my own experiences so far. Looking at other
questions seems to also provide justification against this 50
reputation requirement for comments on others'
questions/answers.  In my own experience, I've seen a few
questions like "how do I do x?" then the same poster has
answered with "in the end I did it like this: ..." where their
solution was perfectly sensible, but there may be some gotchas
to watch for - in this case I want to vote up their own answer
and/or comment on it to point out the potential gotchas, but I
can do neither!  To me all of the above seems justification
against this rep requirement to comment, so what is the counter-
argument and justification for it?  share|improve this question
I think that might be part of it. –  user27414 Sep 30 '10
