DocuCharm is almost done and we are a bit tired. Much was done, still have a long to-do list
Overheard as we document our Data Release 20 at DocuCharm : "I was trying to be artistic"
DocuCharm is going well. We are documenting the local brews
At our Documentation workshop (DocuCharm) in Baltimore. The power going into typing away at webpages, wikis, GitHub, etc could power a small city
