Here's the thing I love about Reid Hoffman. There's no "We-don't-comment-on-rumors-and-speculation" BS with him. You ask him a question and he gives you an answer.So you don't need a bunch of words from me, just go to the jump and watch our final backstage interview of the conference where Hoffman talks about whether LinkedIn will buy Xing and whether it'll file to go public this year.Also, Hoffman names the three other tech companies he thinks can price pretty much whenever they want. (And lucky him, he's an investor in two.)TechCrunch50 Conference 2009: September 14-15, 2009, San Francisco
