I use Strava to track my bicycle rides. Below you can see my recent activity.
I'm not going to do a full writeup here, but for those of you investigating the differences between dotnetnuke and MS CMS I have a bit of advice for you.
Don't bother dropping the $25k on a license for MS CMS, take a look at dotnetnuke, you can't really beat it's licensing costs, how does $0 sound? That's right, dnn is free to use. It's also, IMO, far more simple to develop for, as well as upgrade versions, it's very plug and play compatible with 100s of modules available on the net. Just try adding search into MS CMS, it'll cost you at least another $10k-$15k in fees, while with dnn you can use the standard search, build your own search, OR buy a dnn search enhancement online from NukeSmith.com for $17!
This is all, IMO as always, but coming from a developer who is currently working on a MS CMS project, I'd HIGHLY suggest going a different route!
This website runs on the best open source content management system, DotNetNuke, it always runs the latest release.
