Social Media
I've been using social media since 1996 (listservs and IRC chat), blogging since 2003, and using social networks since 2004 (RIP MySpace ;-)
I'm presently most active on these four services, in some cases for both personal and professional purposes:
Here are some social media sites/pages I've created for professional purposes:
Food Policy Coalition Blog (created this blog & helped the FPC's co-convener get started on it)
PolyCultures Blog (collaborated on the design, curated all the links on the right, & contributed numerous posts)
Sustainable Cleveland 2019: The First Summit (my unconventional use of a blog to collate all the coverage of the first SC19 event)
Here are some other places where I was active in prior years:
Profile on Foursquare (used extensively to document my Local Grocery Policy)
