Like the idea and approach of meetups.

I had a personal blog back in the days, started out with selfhtml and went from there. Somewhere on the journey WordPress came out and I transitioned to it. About 2 years ago I started a personal blog about rowing, since I bought a rowing machine. The blog is written in German, yet often people autotranslate it with Google to match their language, since rowing seems to be a worldwide niche topic.
