I've done that same thing. My posts have become shorter, and I actually find myself 'tl:dr'-ing things, when I would almost always take the time to read it all. I guess that now I've managed to get my post count above 1000, I've got it suck in my mind that I no longer need to put much effort into my posts as I'm not trying to be noticed as much, whereas I used to always try to come across as a semi-sophisticated noob, the kind that still saw the General BBS as a shining beacon of hope amonst NG's dingy atmosphere.
Now I've just shoved this post full of bull-shit analogies to make it longer and so that I don't appear as lazy. It's just a bit of a chore to expand on things when it could all be summed up quickly and neatly with a few short sentences as opposed to vast paragraphs.
Dammit Scarab, how do you do it?
