Untitled Not one, not two, but three guests on this week's PrairieCast. When he heard that the "stop online piracy act" (SOPA) was on our discussion list for the week, BrownWinick's own Drew Larson couldn't wait to drop his knowledge of the subject on our audience. Actually, that's not true. After learning that Larson was planning a seminar to address the topic later this week, I asked him (on way late notice) to sit in with previously scheduled guests Sam DuRegger of Charming Beard Productions and Tej Dhawan of Startup City Des Moines. The five us had a good conversation going not only about SOPA but also lessons to be learned from the whiners in Silicon Valley, what to expect at this weekend's Barcamp Des Moines, updates on the Startup America Challenge (have you registered your startup, yet? Why not? It's easy) and what's next for Silicon Sixth Avenue in Des Moines. While watching the show, feel free to drop over to facebook.com/prairiecast and give us a like. Also, give us a rating in iTunes (audio or video), even if you prefer to watch the show here on Silicon Prairie News. It's cool - we won't tell anyone. Next week on PrairieCast: Emma Peterson of Tikly and Sam DuRegger (back for week two!). PrairieCast is a live podcast, recorded weekly, where a group of entrepreneurs gather to discuss current issues in technology and business that relate to the startup community on the Silicon Prairie and is hosted by Andy Brudtkuhl of 48Web and Geoff Wood of Silicon Prairie News.
