I haven't read the full thread, but I think I can contribute from experience.
I would advise that you calm down about all of this, OP. If you have a search on some older threads, reading at 2 isn't common, and a child who learns to read (with understanding) at such an early age is very probably bright, but it's certainly not an infallible sign that a child is gifted or even exceptionally intelligent.
My DS was "caught" reading at nursery about 3 months before his 3rd birthday and closer observation revealed that he had indeed taught himself to read without anyone noticing. A few weeks later, again with no input / coaching, he was reading everything he could lay his hands on, such as cereal boxes and the Times. However, his fine motor skills were really nothing special - he struggled to hold a pen properly / write neatly for far longer than his less literate friends. Now he's 12, he is still very bright, but definitely not "gifted" in the true sense of the word.
We just left him be, as it really is not a good idea to try to hothouse a child out of having fun. You get what you get - if a child is ready to read and become numerate, they will do it off their own bat. Pushy, performance parenting can put children off learning for life. Just make sure that he has plenty of reading material and let him decide what he's interested in. If he's ready and interested, he'll get on with it himself.
A note for the future - It really is a bad idea to tell a child that he is very bright, or to discuss his intelligence in front of him, as it can make the child lazy/complacent. And it will irritate the hell out of other parents!
