Something involving writing. Words, not code. In fact I'm trying to move towards that goal. Slowly.
That's why I think people should blog more. I have had a meagre 50 000 views for my blog, that only has a handful of articles, and had nearly as many comments as posts, but it is rewarding when people say nice things in comments or email.
To think that in Victorian times, 50 000 people was a lot, and the likes of Shakespear and Dickens posthumously gained worldwide popularity. Sherlock Holmes started as a bunch of short stories, and in this world of Kindles, iPads and Couriers, having your material availabe on the web increases the likely hood of it being read.
