I have talked a lot about how to do 2-3 column and how important it is to have that added in 4.0... and I am glad that you guys have listened. Now, I have another tip to bring to the table....
I haven't talked much about how to revamp the 1 column view. I was recently on TechCrunch.com and I noticed how well they had done the 1 column view. Giving 2 simple and clean tabs for Popular and Latest and making each take up little space and connecting them with a beautiful "Timeline"
I thought you should consider making a template inspired by that concept.
