KDE's Project Silk

Do you really think the developers think that way? They aren't in it for
gratuitous coolness, as much as it might please your ego to believe that.
Don't be ridiculous. There are people working really hard to solve real,
hard problems -- problems that didn't exist in the days when KMail was
first designed, which only surface with today's email load. It's actually
one of the things that is developed commercially, instead of by misled
volunteer enthusiasts -- there are actual customers paying for akonadi,
kontact and kolab.

It's no doubt fun to rant like this, but you're simply wrong about the
developers motivations and priorities.
