I first go to Moca’s web site, seems very simple, not flash and easy to understand. Everything is framed, and it is hard to get lost. Links works well, and they have a slide show on the front page, which is. I guess useful.
Magnum Photos web site almost has the same problems. If you click on any links, you’ll see each sub-link has different identity. Also if you click on a picture, it will load the whole page, which makes you wait to load, and also annoys. Also, even their frames changes on each link.
