He's the Zeus on our Olympus, the Wizard of our Oz, the creamy filling in our Twinkies. Rick's also the CEO of pMachine, and reading his blog will make you very glad of that fact. Expect discussions of business, blogging and coding as well as personal insights into the guy who made it all happen. For me, the appeal of pMachine has always been based on both the code and the philosophy behind the business, and Rick's blog explores both.

Jambor-ee
A web magazine celebrating all things ExpressionEngine! You'll find articles, interviews, tutorials and more- all aimed at folks who know and love EE. Managed by Jamie Pittock, expect to see a lot of familiar faces contributing to the content offerings. Fun idea, well executed.

Derek is the number three man on the EE development crew and the guy most likely to solve the really tricky problems that crop up on the forum. He also has a shiny, shiny website with lots of goodies for the faithful fans. Drop in, skim through his offerings, and admire the shiny.
Low Weblog
Of the bad? Most of Lodewijk's site isn't in English. Of the worse? I only speak English. Of the good? Really cute cat logo. Of the best? A very nice selection of plugins and modules, well worth taking a look. There's an Akismet port, yearly archives, a file management module and more. Check the ExpressionEngine category to find them all.
