I have an opinion I would like to share, from what am reading online, it seems that his last tweet was a bit angry at the programming world, us in a more specific term. Us developers whom have learned so much from him...
What I feel is that it's like an anger wave inside him, that like "alright, people are not thankful for what I do, let's see what happens when everything goes down... now what will they do without me" dunno, but I cannot find an explanation of why even his source codes are down.. really hope he's blessed by god somewhere feeling better and if that's the case, being angry at us, hope he feels better soon.
guys I think maybe we should do him a website, you know like a call for his return, who's with me?
