I participate on several online web-based forums on various topics, including of course, MR, which I visit each day, and on each of them when actually posting I apply the same strategy, developed from "rules" and "netiquette" from Newsgroups/Usenet years ago: if I have something I think is interesting to say, fine, I'll write about it, but when I don't, I simply choose not to waste anyone's time (my own in typing the post or others' in reading it) if it is just something I consider banal, mundane everyday stuff and not worth much of anything and therefore not worth discussing. That is, I'm not going to create a whole post around it. I might throw it in as part of a larger post discussing several things, though. Of course what I consider "banal" or even boring might actually be of keen interest and really enjoyable to hear about and worth discussing on the part of someone else, but I am not a mind-reader and can't know what is in someone else's head..... All that aside, in this day and age we don't have to worry about limited bandwidth, limited online access and all, but just in general we still should be mindful and thoughtful about the use of other people's time, don't you think?
As far as my own post count goes, that has never been a concern to me -- I have more interesting things in life to focus on! (Or, even if my life isn't all that interesting, somehow I can find things more compelling than my post count on any forum.) Again, this goes back to earlier training when as a new moderator on a busy forum some years ago one thing I was warned to look out for was excessive posting activity by any member, as usually (although not always) that indicated the presence of someone or some entity that was undesirable -- i.e., a spammer or spambot, but also there was the situation of legitimate members attempting to run up their post count in order to achieve some desired goal. Lots of one-liners, lots of meaningless posts..... When we spotted such activity and it was pretty clear what they were doing, we took appropriate action. When we got squawks of protest and alarm ("How come my post count suddenly dropped?!") we knew we were on the right track, as how many forum participants even bother to keep track of their post count, and why? Well, I suppose at some level for a few people it is or at a given point becomes a competitive thing and then they really get into that whole mode of pushing ahead, moving forward, forward, forward.....
Whatever. At any rate these statistics are interesting!
