Picked up on Twitter and so true:
I must delete some of my rss feeds, so I just now decided, any blog that apologizes for not posting, they're out. One gone already!
Don't apologize for not posting. If you must, sneak back in and back-date some posts so it looks like you've been paying attention to your blog all along. Or commit to daily posts for a month so that your blog looks fresh. Then collapse your archives so previous months' don't tattletale about former bad habits.
There are ways and there are ways.
