Weird! I just had this post stating my opinions about Riya Photo Search. Riya is the software that does facial recognition to organize and tag your photos.
I closed my post with the idea that if Google were to integrate this functionality into their Picasa product I might be more interested and I’m sure they would improve the user-interface.
Well, low-and-behold Thomas Hawk’s Digitial Connection blog has this post: Google Purchasing Riya?
Niall Kennedy has more details here and of course Om Malik would have something to say here too, most of which he believes is just rumor and speculation at this point.
