A good question. I think it comes down to it being a competition for bloggers, rather than a competition for people who can create a one post blog. As for 'topic', this blog, along with many others are personal blogs, they reflect the person who is writing them - I could stop writing about ambulance work if I so desired and change to writing about knitting. So I don't think that personal blogs have a 'topic' written in stone - which is what annoys me a little when people moan that I haven't written about ambulance stuff for a day or two, it's my blog and I can write what I like. Never forget that I don't get paid to write this blog. So an occasional post about something in an effort to win something isn't 'evil', at least not in my eyes. Thanks for making me think though.
