One thing that came out of last night's meetup in NYC was the agreement that there should be a set of common tags by which everyone can flag content around the web that relates to DIYcity.
Good idea, of course.
So from now on, if you are tagging something up in delicious, or flickr, or whatever you use, and it relates to DIYcity, tag it with 'diycity'. If you're marking up a Twitter tweet, use the hashtag #diycity.
And if it relates specifically to DIY NYC, mark it as diynyc. If it relates to DIY Melbourne, mark it as diymelbourne. Etc etc etc.
In that way, DIYcity can start to escape the confines of the website.
