nice, i wonder if you can mimick the Zite app, which i believe also strips news from multiple sources then reformats it to its own look/theme/feel, only their not worried about data useage.
It's a good idea tho. would be nice to have the next best thing to opera.
Considering how integrated our stock browser is, its a shame there cant be a toggle switch for the normal browsers/webkit to act normal or in your new method, theres the isis code out there to mess with as well for open webOS, maybe you could just abuse the normal browser to do as you wish and repackage it.
