Some great advice from Philipp Lenssen at Google Blogoscoped: Good Blog Writing Style
Interestingly enough, Lenssen quotes Danny Sullivan, Editor of Search Engine Watch, where he rants "Google Blog: Please Get Descriptive With Your Headlines!" But Sullivan's post links to Good Blog Writing Style from Philipp at Google Blogoscoped! Kind of a Mobius strip.
Either way, they sock it to Google's own official blog for bad writing... including cutesy headline that leave you guessing what they mean. (I gotta watch that myself! Nasty habit of wordplayers and wordriders!)
