Cordillera Interactive launched two more Montana site rebuilds this week in its Operation Tune-Up project: in Billings and in Helena. Here's the before (left) and after.

The changes under the hood matter most in this project, as I described last week: lighter page weights and scripts mean faster load times and fewer nagging browser incompatibilities. Visually, we cleaned a lot of things up, but the differences should not be jarring or confusing to an occasional visitor.

We'll finish Montana sites quickly then move on to a series of launches in early October. As always, I welcome comments from my friends in the user experience and Web programming fields.
