Granger's 'Light Table' was always an experiment in my mind, but I'm kind of sad that he dropped it and moved on to the next 'let's fix' programming thing.
A co-worker uses it at work exclusively for editing markdown documents. I find that a little funny.
I had great optimism for LightTable, helped Kickstart it, but was disappointed with ultimately for the very reasons he outlined at the beginning of his talk: it couldn't shift me from emacs. It's not religious for me, but I could try and fail two or three times over in the time it took me to boot lighttable, figure out how to load my code, eval it and begin to debug it.
I enjoyed this presentation though. His Eve does strike me as a sort of proto-semantic web, although I'm warier of pouring my optimism into it this time though.
Was it a dead-end?
