Stream of Thought/Not caught be spell check

I sometimes go back and read old posts of mine as well as the comments Every time I do, I notice several typographical errors, run-on and incomplete sentences, and even a couple of sentences that I have to read over and over again to figure out exactly what I meant. You see, blogging comes during rushed moments when I know I should be doing something else. Thanks for reading and muddling through the incoherency. And yet, I will probably have many a more instances when this problem will occur. Just to let you know.
