I reckon it may correct next week, but this will certainly clean out weak shorts tomorrow and possibly monday. Looking at the chart, I think this stock might be in the process of making a parabolic high in the 250-350 range this month or next. I hope it will not, though, as it would come too early.
The potential of this stock is absolutely tremendous, it's not only about recruiting, not only about social networking, it's about everything work related, i can imagine a vibrant ecosystem of "apps" just like the one Apple or Facebook enjoy. This is truly a "couple hundred billion" dollar stock in the making.
