I saw this image on some folks facebook wall:

The thing that bothers me that it is focused on L.A., which is complete ignorance. I would get it if it only read, “Oh, you took a level one improv class?” That makes more sense to me because people think they take one class in improv and they’re masters at improv. I abide by the Gladwell idea that you put in 10,000 hours to master a skill.

The flaw in the idea that you “will not learn good improv in L.A.” is proven by the fact that a ton of old-school Chicago improvisors teach at iO west and a ton of NY improvisors teach at both iO west and UCB. To name a FEW: Billy Merritt, Anthony King, Chad Carter, David Harris, Joe Wengert, Shulie Cowan, Craig Cackowski, Brandon Sornberger, Dave Razowsky, Seth Weitberg, Eliza Skinner, Eugene Cordero, Suzi Barrett, Susannah Becket, Julie Brister, Jill Donnelly, Tricia McAlpin...and tons more.

There are also good teachers in L.A. that I have yet to take that have produced L.A. improv talent that I admire like Betsy Sodaro and Rene Gube. 

There are also GREAT classes in L.A. for actors who are much more timid about approaching improv at Carolyne Barry and Second City.

Please educate yourself before reposting something like this, or rewrite it better.
