No offense, but as an engineer with no particular knowledge or experience with marketing, I don't see very much actionable advice in your items. I see a lot of ways to screw up (emailing bloggers wrong, picking wrong marketing person, waiting to long to market), but a dearth of advice for not screwing up.

Maybe the positive advice will be in your Guide (haven't clicked the link yet)?

EDIT: OK, I should have clicked the link first. :)
