Kloosterman.be. One of the sharpest looking family genealogy sites around. They use The Next Generation of Genealogy Sitebuilding (an online, interactive genealogy application).
They have done a great deal of work on presentation and functionality. Usually, family sites have one or the other. It’s obvious they take a lot of pride in their work (and deservedly so).
They cover multiple languages (not an easy thing to do), plenty of content to keep you interested, and it’s updated often. Very easy to navigate.
A setup like the one they have, requires a great deal more work than many people are either willing to do, or knowledge that they don’t have, but software like TNG does make it easier.
