Mobile newsreader service Mobispine is acquiring NewsAlloy, an Ajax, web-based RSS reader, intending to merge the two in to a “seamless” product offering personalized newsfeeds across desktop and mobile. The acquisition price is not disclosed. The NewsAlloy website claims 11,331 registered users, and Stockholm-based Mobispine says it has over 300,000 active mobile users per month. Somewhat ambitiously, they are targeting 10 million users for the combined operation. The online RSS reader game is frankly a tough challenge, in the face of mature offerings from bigger players like Google (NSDQ: GOOG) Reader, Bloglines and easier alternatives like My Yahoo (NSDQ: YHOO). But Mobispine says its NewsAlloy combination can offer “a welcome change” that can be used by “everyone from tweens to seniors”. It also uses the word “murfing” seriously in its release.
