Last year, the Write Weekly didn't quite live to its full potential. However, I think it deserves a second try. So as was said prior:
"Publish a written piece each week, no requirements. Hopefully something you are proud of, but practice is better than nothing!"
Oh and if you want to boast of your streaking on twitter, use the hashtag #WriteWeekly to do so with class!
