Last week SimpleGeo and their partner Stamen Design jointly released a project they have been working on together called Polymaps. It’s absolutely beautiful and a stunning example of what you can do with the SimpleGeo API. They’ve released the Polymaps source code on GitHub so any developer can quickly see how the API is used, play around with real production code, and modify the base examples for their own use.

I had a new experience today. At 7am I had my first MRI at the Boulder Community Hospital. I was a little nervous, although I’m not entirely sure why. I was in and out in 45 minutes – it was fascinating. I hurt my lower back about five months ago (actually, exactly on March 13th at about 1pm at my parents house in Dallas). I went for a two hour run and then took my dad to Fry’s for his birthday to buy him a new color printer. As I unloaded the printer from the car, I lifted correctly, but then twisted left and immediately knew I’d screwed myself. I rested a week and started running again in advance of a marathon in mid-April in St. Louis. I had a great three hour run in Charlotte the first week of April and thought I was ready to roll. Amy and I drove to Santa Fe the following weekend; when I got out of the car when we got back to Boulder I had enormous lower back pain. I got a massage the next day (big mistake) and when I woke up Tuesday morning in a hotel room in Seattle I couldn’t get up off the toilet, nor could I completely straighten up. Four weeks of rest and three months of intermittent running with regular recurrence of back pain in the same spot after a few days caused me to finally decide that I’m hurt and need to figure out what’s going on.

Ever since I switched to the Mac, I’ve had N (where N is a suitably large number) tell me that I should switch to Gmail from Exchange. I finally decided to try it for a week and see if it works for me. Given my Mac experience – where I had to commit and really use it, I’ve decided to do the same on Gmail. For now, I’m just going to use Gmail (instead of Google Apps) because I don’t want to go through the hell of switching the feld.com domain since I’ve got a bunch of other people (e.g. my family members) on it in a variety of configurations. That’ll limit me a little as I won’t be able to use the Apps Marketplace, but the benefit is I’ll be able to mess around with a variety of other Gmail stuff.

I get a lot of inbound resumes from folks looking to relocate to Boulder. I also get a lot of requests from local CEOs for candidates for various positions. I do my best at connecting folks, but I’m sure plenty of connections slip through the cracks. So – David Cohen of TechStars (who has the same thing happening to him all the time) and I have created a new private email list for CEOs of Boulder-based companies. We have started to email qualified inbound resumes to this list. By qualified, I mean that it’s a real inquiry, rather than a generic “resume spam email” which is the only email I get that I won’t respond to.

Ah – the joy of a meme. Today’s meme is “The Web Is Dead.” Whatever. My favorite article about this in the past 24 hours is The Tragic Death of Practically Everything – this is basically what I would have written if I’d had time today. This latest round apparently started with the new Wired cover story “The Web is Dead.” Yeah, I read it. My reaction to it was “whatever.” Are books dead? Is email dead? Are memes dead?

My partner Seth Levine has an outstanding post up today about the freemium model. It’s titled Pricing models, the freemium myth and why you may not be charging enough for your product and is worth going and reading right now. He covers a bunch of stuff, nicely divided into the following topics: Beware of too many pricing tiers. Have a clear delineation between product tiers. How about overlay features that you charge by the drink for? Be careful what you put a tariff on. The freemium myth. Don’t be afraid to charge for your product. Beware the long “trial period”. Seth has become “the pricing model guy” at Foundry Group – we’ve been dragging him into every pricing conversation whenever they come up.

On Wednesday I did two interviews with Mark Suster – one for This Week and Venture Capital and then one before the LaunchPad LA event. TechZulu recorded and broadcasted the second one. The first three minutes are kind of funny as we didn’t know they were recording so we were horsing around talking about funny drinks and the legalization of a particular type of medicine. The actual investor that happens over the next 45 minutes is about TechStars, entrepreneurial communities, and some of the stuff I invest in. Mark does a good interview – he can have me back anytime.

Now that my complete and total infatuation with my Mac has worn off and shifted into delight and love, I’m starting to explore the weaknesses of the Mac for not other reason than I’m trying to figure out where the real rough edges are. So – if you are a Mac user, I’m very interested in the things you don’t like about the Mac, especially the things you hate. I offered up the Address Book as a burnt offering the other day. Anything else out there that blows?

I’m totally wiped out after a full day in LA that included a board meeting at Oblong, a 75 minute interview on This Week in VC, strange drinks at Volcano Tea with some LA entrepreneurs, another interview on TechZulu before the Launchpad LA event, and then a Launchpad LA event. Mark Suster – who is everywhere on the LA entrepreneurial scene – was my gracious host, interviewer, and master of ceremonies for the day. I predict he sleeps well tonight.
