Apple WWDC Keynote Observations

I managed to watch the Apple WWDC keynote today, and wrote up a few first impressions. This is by no means a list of the announcements — consider it my list of observations about what the announcements mean: Apple is converging the mobile and desktop experiences on an OS and application level.

How To Buy Expiring Domain Names: Lessons Learned

Lessons learned buying domain names I’ve been in the market for some new domain names lately. It isn’t 1997, and it’s not so easy to score a good domain name anymore.

And previous attempts to create a tablet market have failed pretty badly and at great expense. Just 2 days ago, I posted some […]
