I have updated my Midwest events page with new information about upcoming conferences. Some of these events (like Strange Loop) sell out pretty quick, so be sure you sign up early to secure a seat and early-bird pricing (where applicable)!
The two best St. Louis developer conferences, St. Louis Day of .NET and Strange Loop, have become sponsors of the STL ALT.NET meetup group! Each will be donating one ticket to their 2011 events in August and September, respectively. I’ve attended both of these conferences in past years–they are top-notch events that every St. Louis developer should attend.
See the events page for more details on each conference.
