I missed Rob's talk on AntiPatterns during Code Camp III, so I am looking forward to this one. If you aren't familiar with what they are check out http://www.beantowndotnet.org/ Sam has put some good links out on the site in the left column ... some interesting things in the Anit-Patterns Catalogue (interesting names too).
In case you missed it, last week Sam announced, that I am joining the group as the Membership Coordinator ... so just to be warned - you will be hearing more about the Beantown.Net group than you use too ;)
