Given the fact that opinions tend to differ, here's a few blog posts from other committee members that I am aware of.

Did I mention I feel it's time to get technical again? I am feeling saturated with politics :) Next up: A WSS3 custom field type, boasting a field editor UI using IFieldEditor, WITH persistence of custom properties (there's a bug there), and using the WSS PickerDialog to allow the user to search for items. I only need to finish some of the CAML rendering. Anyone that can help me write CAML rendering for a SPFieldMultiColumnValue for which I don't know how many columns there are? Patrick, I hope you're reading this :)
The field type? A record lookup field. It is similar to the normal LookupField, only this one allows you to lookup a list item in another list. You can choose to include some of the other list's columns, and use the PickerDialog to choose which record to link to. Cool stuff I say! Stay tuned...
