NewsGator Technologies will be announcing "a MAJOR acquisition" at the Web 2.0 Conference on October 5-7. Hmmm, I wonder who it is. Looking at my RSS Space spreadsheet, Newsgator is one of the leading vendors in the Reader Services category. They also have a presence in the Search space.

I wouldn't be surprised if they acquire a lesser but still bright light in the Reader Services category - say, del.icio.us or NetNewsWire.

But as I said, Newsgator is dabbling in search - both indexing and white label. So if anything I'd probably lay my bets on a search-related acquisition. Perhaps Feedster - Scott Rafer recently left Feedster for more mobile pastures. Or maybe even Technorati!

In another acquisition rumor, SVW reports that Moreover will be bought by "a much larger multi-national company". PaidContent.org says it will be "a Silicon Valley-based public company (NOT a media company)."

The safe bet would be Microsoft because of their existing relationship with Moreover. But they're not SV-based. Hmmmm.

Let the speculation begin! What's your guess?
