Sony Pictures has been keeping a Spiderman weblog since April of last year. The author is Grant Cutris, Co-Producer of Spiderman 2. I think he has done a really good job. He give a great behind the scenes view of S2 and answers questions from specific readers in his posts.
They have doing some interesting things. They have an education area to teach readers about weblogs. They have S2 blog templates that you can download. I also thought it was clever that when you subscribe to the RSS feed, you got all the entries from the beginning.
The biggest mistake they make is there are no permalinks. Here is the link to the main page and you can find the blog under the Daily Bugle.
I have never seen this blog come up in my reading. Does this show how important permalinks are?
