The only way I'm going to start hating on his tweeting is the day our PPS Sinks, and he starts tweeting selfies on random beaches in exotic locations, while drinking cold sasparillas. Mostly because I'd be jealous. ;)
However, I cannot see either of these things happening, so I think his tweeting is great, makes me feel closer to my investment, and able to relate to him and $ONCS, it also shows his personality, and he seems to have a great one, which is important. Another good thing about some his tweets, they are generally based around well being, and social responsibility, I think these are two very important things when you're CEO of an up and coming Biotech, he's portraying a very good image, for himself, and ONCS. I like it. $ONCS
