I was one of the unlucky ones that didn't make it to LotusSphere 2007, so I have been spending my few free night reading and catching up with the news and opinions rather than posting.
I'm gradually working through the presentations that interest me. I liked Nathans & Chris' interface presentation. I think that stuff like this should be mandatory training for Notes & Domino Developers. Some of the techniques apply just as well to web apps too so it's worth a read.
I learnt early on in my developer career that some nice graphics and icons can make a world of difference to the perception of an application. The investment in learning photoshop has been well worth it.
Anyway back to the reading....
