Well, it's Monday afternoon and still no official word either way.
However, Om Malik, who first broke the news of a possible acquisition, has updated his post saying that he's tentativly confirmed the deal with Google paying about $40 million for the company.
A clue? At the moment, the Riya web site is online but all of the content has been removed. It states that the site is getting some "TLC."
The company blog has no acquisition news but does say that a second Alpha version of the product will be released in the "next few days." Our post on Friday also included a bunch of info/links on image/face recognition searching.
