I'm going to edit as I find more.
From my daily comics trawl:
Anders Loves Maria
Count Your Sheep
Dominic Deegan
Dresden Codak
Girlyyy
Real Life
Scroll down the page for Sam and Fuzzy
Scary Go Round
Shortpacked!
Skin Horse
Templar, Arizona
Unshelved
Wapsi Square
Found scattered around on the internet:
Dueling Analogs
Prometheus
A list from last year's Ryan Estrada Day is at Flight Comics
And, as completely expected, Fleen enters the fray as Gary compiles a more extensive list.
