Liz Gannes and Niall Kennedy report that Rojo Networks, a social feed reader, has been acquired by Six Apart, a blogging startup.
Liz points out that "there are getting to be fewer and fewer RSS reader companies."
With the entry of the giants -- Google's Google Reader, Yahoo's My Yahoo, Microsoft's Live.com, Mozilla's Firefox, and Ask's Bloglines -- this is not surprising. There is no room for little guys when the big players come in, not unless the product is unusual and well differentiated.
I have long expected the same thing happen to vanilla blog search, but I have been surprised by how well Technorati has done against competition from Google Blog Search and Ask's blog search. Things may heat up more when Microsoft and Yahoo fully launch their blog search products.
