@sozobe,
The thing about online communities and personna is that people see online postings in a snap-shot form and format. So the perception is that for that moment in time...subject to an individuals perceptions about what those word's mean to them at the time...they formulate an opinion - sometimes a wrong perception or even a superficial one.
However, an injustice may occur as the person may not go back and read or re-read every word or every comment that person wrote. So creation of an objective opinion of any individual can be variable....and/or even unjust. Sometimes posters don't edit their posts much or at all and as a result, stream-of-consciousness posting results. This can set a bad example and p-people can misrepresent themsleves, but that is not exactly the issue here.
Using a general perception of my online personna as a personal example, by some (or maybe the majority) of the A2K community, the perception is that I can be a major scold. Over time, I perceive that many people avoid making comments and engaging with me. I'm neither sad nor happy about this, as I am aware that it's a reaction to a snapshot of me..or better said..my online personna on A2K. This is only but a slivver of who I am. Of course, like many I'd liked to be better liked, but it's not a goal I seek. "It am what it am!"
Objectively, I know that the perception (of being a scold) has been true, at times. However, there are many times that I have hung in there with some individuals and/or posts and provided my strong support for people, too.
However, the nature of online communities and perceptions is that only a snapshot of that person is taken..and a superficial view is formed. People often don't got to the trouble of one-on-one discussion or in-depth review of more than a handful of comments.
So people on the whole don't get to know very many people at all well. And rarer still is when people go to the effort of meeting someone or dialogue with them as you would in real-time relationship.
OK, pardon my ramble, but suffice it to say...allow this post to be a message: when you think you know someone, don't be sure that you really KNOW them. You may know an online personna...and you are reacting to something that may NOT be the whole measure of whom that person REALLY is. the perception is only a snapshot...without much nuance.
