There is a stereotype going around that having a straight face and being serious amounts to professionalism. What many people do not realize is that being serious and always keeping a straight face means the lack of ability to exhibit a sense of humor. It can be a shortcoming, and it is definitely not a sign of professionalism. Professionalism has nothing to do with being quiet or smiling.

Personally, being positive even in negative comments is a good thing. A professional person can balance out being negative and positive. If a professional person can let someone know that even in a negative comment one can find positive things or infuse sensible, relevant and useful humor, that professional person can probably build some kind of a positive bond on even the smallest level with the commentor who left the negative comment.

Note that I said “person” and not “worker”, since professionalism has nothing to do with work.

Thanks again Vivien, your comment helps shed more light on the concept of maturity I was referring to.

Also, if a blogger can respond to a not so positive comment with a good sense of humour that would make the commenter feel bad about being negative, in my opinion it shows the high maturity level of that blogger.

And I do wholeheartedly agree with the three maturity qualities mentioned by Ronald.

You are right; confidence, logic and communication does play an important role in how someone “appears” to be mature, regardless of whether or not they really are mature. I am guessing the idea of being pleased by something a person exhibits blinds people into giving that specific person benefit of the doubt when it comes to maturity? Or maybe people associate maturity to confidence, which is somehow associated with the traffic and amount of money one makes through their blogs. What do you think?

Confidence, logic, and communication play a big role into how someone is perceived.
