If you want to be popular choose popular topics, explain them in the most clear (KISS) way, then keep doing it. Now and then post a blog with some religious stuff in it. Post obvious stuff but, put lovely pictures, cure kittens and try to explain one simple thing like no one knows it.
Unfortunately more and more blogs are getting empty, good stories, lots of bollocks but not a damn real thing, or the same things over and over with a new narrative...
So please, please, please don't improve your technical writing style to be "yet another 'I write nice blog posts about mass technical(ish) people' blogger.
No offence to Joel or Jeff, they are doing something nice, but we don't need more Joels or Jeffs, that area already have been covered.
Write pure technical blogs and deep subjects if you dare, not stories.
