Here's a cautionary tale for you.
I was just happily typing away at the next update for this blog, forgetting that I still had a redundant text editor open in another window for a post at The Accumulator. Somehow I wound up typing what was meant for this blog all over that one then clicked 'save'.
The version of the blog entry that was open in the text editor wasn't the most up to date one anyway. Basically sent a bunch of stuff I'd written into internet oblivion and had to do it all over again.
Be careful out there.
UPDATE: More mistakes and madness - I accidentally linked to blogpot, which appears to be some sort of Biblical site.
