well, they have recently created a new site about bookeen :
http://www.netvibes.com/bookeenblogs so that's another source for info.
but also, bookeen is in paris, and the month of august in paris is dead : half the country is on vacation, and the other half can't get very much done because of the first half being on vacation... really, nothing about work happens in august.
so there's no point in expecting anything before september.
the good news is, september is coming soon !
