With the recent proliferation of camera phones and hiptops, I figured it was only a matter of time before slick tools came out to support them. I've heard about all sorts of home-brew solutions, but pop2blog looks like the first generic mobblog solution, and it seems general enough to work with camera phones and plain email as well.
It's interesting that the integration of blogging tools with email services is just happening now, when many blog authors and app developers are getting devices that rely on email for getting messages and photos out. For at least the past two years, I've often encountered people new to weblogs, but experts in computing and the internet ask for email-to-blog functionality in all their tools. This is especially true in the business world, where email has been a mainstay, and blogging is nascent. And for some people, email is their preferred interface for all online transactions, and they're surprised when they hear that built-in support for email-to-blog posting is almost entirely nonexistent.
I know that bridging the protocols and standards between email and web-based blog applications isn't the easiest thing to accomplish, but why weren't developers listening to their users for the past couple years?
