what are blog do's and dont's

I don't think there should be dos and don'ts of blogging as long as you are plagiarizing somebody's work. Blog away to your heart's content.

Post your blog for review, may be there people can tell you whats right and whats wrong with your blog 

Yup, the lists are truely infinite....

As far as i can remember, do's & don'ts for a blogs are infinite.... May be your question should be more condensed to get your doubts clarified :-)
