Earlier, BoomTown reported that MSN exec Jeff Dossett would leave the company and possibly soon join Yahoo, where his longtime friend and fellow Microsoft alumna Joanne Bradford already works. Not true, says a Microsoft flack, who tells us: "Jeff Dossett is leaving his position as MSN’s US Executive Producer to seek other opportunities within Microsoft." So either Swisher got it wrong, or Yahoo got outbid for Dossett's services at the last minute. Given Swisher's red phone access to Yahoo's inner sanctum, we're guessing the latter is true. We haven't spoken to Dossett, who once climbed Mount Everest to raise awareness for AIDS and HIV in Africa, but we imagine if we did he'd say something like: "Join Yahoo, now? Too risky."
