Now, I've had errors in comments on similar blogs (including mine on occasion) in the past, to the point where I always just ctrl-c my comment and then hit preview; after preview it usually works.
But I think I only had those errors with Safari, whereas now I'm a firefox man.
I am curious, for anyone what reads this, if they've had problems commenting--and can use that method to successfully leave a comment. Regardless, I'm looking at either a fix for the comment issue or a change of venue. Especially because I seem to be finding many threads asking for a fix to the comment issue, but none showing that such a fix exists.
