Miro Svrtan: Starting/organizing a developer community: ZgPHP meetup
The year 2011 was a great success for developer communities in Zagreb. Although mobile developers started in 2010 with Mobile Monday, web developers were a bit shy and Ruby developers started first, then python meetups started and in the summer few people urged/pushed me to start organizing PHP Meetups. Besides colleagues I did not know a lot of PHP developers so I needed to spread the word about it. Twitter was the first step and it paid off. With only a few retweets there were already 10-20 people interested.
The post talks about the growth of the group, things they wish they'd done better (like involving local companies) and their work to create a custom logo for the group. If you're in the area and want to find out more about the group, check out their main page.
