Blog dump

So it's been a while since I've written. I feel almost guilty. I don't really know how many people stop by here to see if I've updated, but I figure if they do long enough, and I haven't, they'll of course stop reading. Well hopefully the dry spells won't last too long, and the 3 readers that I have won't stop stopping by.
I could of course make up lots of excuses. I've been too busy. My cat keeps sitting on the keyboard while I'm trying to write. The network is down. I was kidnapped by space aliens who removed by ability to write complete sentences. Etc..Etc.
But, I suppose it's more a question of laziness. Sometimes when I come home from whatever after work activity I've been at, I'm just not in the mood to sit down and put some thoughts on the screen. Once I actually do it, it's a bit cathartic, and of course it doesn't really take that long to do a rough blog. If I'm actually trying to say something intelligent, that's an entirely different question, but sometimes it's fun just to do a brain dump (like this post) and sorta see where it goes.
If it's completely unintelligible, then such is life. So, out of curiosity, how do the various people who happen to pop by my site do their blogs? Do they just write, run the spell check (maybe), and go? Do you think about your post, write it on paper, and edit many times before you post?
I'm curious about the basic writing process for many of you for the various bloggers. Is this a brain dump, or a carefully planned exercise in thought. Thanks, and may the blogs continue...
