As Damien Katz locked his thread about Formula Engine Rewrite (btw, his exposure is a very good reading, and I really appreciate that), I could not post this:Maybe IBM killed the spirit, but without IBM, Iris and Lotus would maybe also not have gotten the marketing force and publicity which IBM Lotus Notes got now.Now it's Big Blue vs (or and?) Microsoft.Although I also see IBM as a big dinosaur, I also see Lotus and Iris still as teams within. They know it themselves, using their "secret upside down" codex in LotuSphere :)Microsoft and IBM both have their bad and good sides, and I could list hundreds of things which I don't like about both, and which I like about both. However, in the end all what counts is what you use. I use certain Microsoft products, certain IBM products, and I think those are the best of both worlds, and those are the best not only in their worlds.
