Comments
  1. ## UPDATE on MerbAdmin

    I rewrote MerbAdmin to dynamically inspect your models at runtime (as opposed to using a code generator) and pushed it to [GitHub](http://github.com/sferik/merb-admin/). You should check it out. If you find a bug or want a feature, I’d love to hear about it.

    Also, a [video of all the GoGaRuCo '09 lightning talks](http://pivotallabs.com/talks/66-gogaruco-lightning-talks) is
    now online.
