Here's a link to Techrepublic's article on how to become a better blogger. Pure commonsense, though nothing outstanding.
I think an honest effort on your part is the key. And not to think of monetizing before you have gr8 content is important. Though I need to remind myself on that also!!
Read an article trashing Bloggers as half wits, failed writers and mercenaries among other epithets. The writer obviously has not seen the best of blogs which add value to the community. Though there are a lot of rubbish blogs and blogs catering to the narcissism, the same can be said about journalists too.
Isn't it a case of pointing fingers at others without realising that three fingers point back to you and the fifth to God!!
