I wish that they would both come up with an app that is a dedicated browser for the Sheldon Brown page, and also clean the site up and continue to expand/improve it.
Sheldon put a lot of blood, sweat, and tears into that site when he was alive and it is a great resource. But it is slowly eroding into a less useful resource as progress and new knowledge marches on.
Harris Cyclery could make something really special (and profitable) out of it if they only had the vision and a few talented people to run/maintain/upgrade it. And an iPhone/Android app would be awesome for fast/quick browsing of the content and many tables/cheat-sheets that Sheldon put into the site over the years. As good as it is, it could be even better.
