Some interesting bits are beginning to trickle in regarding Windows Live and developers. At trickybusiness, Richard "Tricky" Bassett blogs about creating celebfavorites.com, the demo Virtual Earth mashup that showed you some celebritie's favorite haunts. What's interesting about this entry is that it's not written from a coder's perspective, instead focusing on design and branding. Bassett teamed with Dr. Neil Roodyn, of Via Virtual Earth, to develop CelebFavorites. There's more about Dr. Neil, Tricky, and developing around Windows Live at Re:merged.
Another interesting third party app comes from Frameworkx, creators of the Custom Domains Manager. Gus Pinto has released a neat little app for Windows Live Messenger, the Auto Reply Add-In.
