Over the past 10 days, I've presented IronRuby to about 1000 people. I gave talks at RubyConf (slides [6.4MB]), the Charlotte Developer's Guild, an internal talk in the Microsoft ECS series (slides [5.4MB]), and a keynote at the Patterns and Practices Summit (slides [5.4MB]).
My favorite talk was probably the ECS talk since I had 1.5 hours to do the talk (for internal folks, the recording has already been posted). There's a fun sequence of slides which compares and contrasts Ruby with C# 3.0. It's striking how C# with its local type inferencing and terse anonymous delegate syntax looks quite similar to Ruby blocks.
The recording for my RubyConf talk should be ready soon; keep an eye on the RubyConf site for an ETA. BTW, Microsoft sponsored the recording of all of the talks at RubyConf this year, yay us :)

Great stuff John,
I look forward to seeing the RubyConf videos :)

Hi,
IronRuby is floating in Apha -2 stage currently
What is the expected time frame for IronRuby to enter Beta Stage.
Shall we have Beta -1, Beta-2, followed by CTP and then RTM.
Pl. specify the time frames.
Thanks

@SoftMind:
We don't have a schedule planned for when we're going to call it a "Beta". We will likely call it a Beta when we can run some significant set of programs (likely Rails) so we're at least 6 months out from that.

Any hope of getting those slides in PDF format for those of us without Powerpoint?
