I met Ikai through the Silicon Valley Rails Meetup, which I co-hosted back in 2008-2009 and which met at LinkedIn HQ in Mountain View. This post is a great contribution to the recent discussion about Rails at LinkedIn, and I hope it gets the attention it deserves.

Hey Michael!

Was there a recent discussion? I'm fairly certain everyone has moved on from Rails, and I'm not sure if they're still using it anywhere at LinkedIn. There are a few folks using JRuby, but I believe they're using Sinatra:
