Creativity

Often I get writers block, sometimes it last for days, othertimes weeks. When I emerge with new inspiring ideas they fall in one of three categories.

1. Something useful often techical - these sorts of posts often end up as articles like my recent 10 useful mac tips article. If I'm lucky these sorts of posts go all around the net getting me a few hundred thousand new visitors.
2. Rants - these posts not unsimilar to this one are highly sarcastic, humorous fast paced and often hard to follow. Phrases such as 'much love' are used and more recently photos of Gordan Ramsay saying 'Done' (like he does in the fword).
3. Unfinished posts - I often start writing top X lists only to write the first three or four and run out of good ideas. Either I fill it with a few lame entries or give up for another day.

I guess what I'm trying to find out is how does your writing style change depending on your mood and inspiration? In this sense is writing a blog different to say writing for a newspaper or magazine?
