What should I build to support my web app?
nfnaaron: "6) Mailing lists. I did this 3 years after starting my business. Knowing what I know now makes me sad I waited that long. MailChimp is an easy snap-in."I remember the other day you stressed how much you don't spam your customers. So I'm assuming this is an opt-in thing, but:  - Do people really opt-in enough to make this worthwhile?
  - What do you do with it that makes it worthwhile? New product announcements?

"15) Backups for all that stuff that isn't on the database. I let Slicehost handle that."They just back up whole images, and restore them (plonk) to your slice, right? What do you do for data that's not in your database, that was created after the most recent backup? And do you restore to your main slice or a temporary slice?
