Exclusive: Yahoo's Communications Products Head Jason Titus Departs

In what many sources at Yahoo characterize as a blow, Jason Titus (pictured here)–who heads all communications products for the Silicon Valley Internet portal, including its powerful Yahoo Mail and Messenger–is leaving the company soon.

Titus, who has been at Yahoo (YHOO) since 2004, was reportedly considered a key exec by CEO Carol Bartz in her attempts to revive the company.

Yahoo confirmed the move when BoomTown asked for comment.

Sources said Titus wants to take time off and has no plans to move to another company.

Michael Curtis, a close and well-regarded colleague of Titus, will take over as interim head until a replacement is found.
