Ask HN: Basic Spreadsheets/Data Management for Startups

Hey HN. I'm the more technical of my company's two founders, and I'm the one who handles all of our spreadsheets and other misc data. My partner is exceedingly bright and motivated, but seems to have a mental block when it comes to Excel/Google Spreadsheets. I'd love some resources that I could point him to. Sure, I could just fire up the ol' google search, but I'd really like specific links that might even be tailored to entrepreneurs.

In addition, I'd also like to show him some articles about what to -do- with data once we have it. Kevin Owocki had a great piece about logging everything so you can manage everything, and I'd love to show my partner more pieces like that.

I'm not a frequent poster, so if I've missed a vital piece of Ask HN etiquette, yell at me.
