I don't think you should sit behind your table and hit F5 and watch if there is a new block. The luck/variance is a very big factor. You should realize that the luck is only eliminated in a very long timeframe, that being 14 days+. I for example mine at Slush's pool (Which is usually around 10 percent of the whole network) and I have seen such streaks of bad luck - even 17 hours with no block found. Then there were five block found in 15 minutes. That's just the way it works. If the market is so irrational and bases the buy/sale of AM shares on the luck in last 6 hours, then that's another thing. It seems to me however that the weak hands were already shaken off and now we're stable around 2.5BTC. The share price will probably start rising again after the new chips are developed. I think there will be weeks now with pretty weak dividends and pretty low share prices... All of that said I don't plan on selling any of my shares
