I'm not quite sure how many people read my blog (see footnote). I can be sure that about a thousand people take the PL/SQL Challenge every working day. They take the time to visit the site, read the question, think about it and come up with an answer. I assume most will actually check the correct answer the next day (and maybe think about that too). So if I can phrase my article or concept in the form of a question for the Challenge, I can reach a much wider audience that I do through my blog. And they will think about what I wrote.
So far I've had one question published (25th of Jan 2010), taken by 1090 people with a typical time of 2 minutes and about two thirds got it all correct. And about 200 submitted a survey afterwards. That is a lot of eyeballs. I've got another one coming soon and I recently submitted a third.
So if you've got something you want people to know, whether you have an existing blog or not, if you can phrase it in the form of a PL/SQL question, go submit it. Alternatively, just go and play. The challenge awaits.
Google Analytics talks of about a thousand page views last month (though misses a week when I did something and lost my old stats). Blogger stats says about 2,700 which is more comforting. I expect some will pick me up through an aggregator and won't get counted and I'm not sure if a bunch of people who take my feed online, eg though Google Reader, are counted individually or not.
