At ReMIX I had the pleasure of interviewing Lucas Sherwood from Lightmaker (which reminds me, must get down to Melbourne again soon). It was an on the spur of the moment interview but in it, we talk about a lot around some of the challenges they faced coming from the Adobe toolset's over to our new product(s).
Lucas is one of the RIA Producers in this industry that I respect, as he's approach is pretty straight forward and rarely cares about which team is better then the other. Lucas has a quite an interesting background dating back to Allaire days (Coldfusion) through to present day.
At any rate, I hope you enjoy the interview and can use it in some way.
