If you're an author and you need a down-and-dirty website fast, then follow Seth Godin's strategy for creating a website in a few hours by linking a blog, a Squidoo lens, and a Flickr collection of photos. He says you can do it all for $60 per year. You can read his blog post at: Seth's post.
But that's by paying Typepad.com $5.00 per month to host your blog. Alternatively, you can host your blog here at Blogger.com. You go to Blogger.com to set up a blog, which is then actually hosted here at blogspot.com. Same company, just different URLs.
You can easily set up a blog here with your name or your book name so it reads something like: http://yourname.blogspot.com. Then go over to Squidoo.com to set up a lens (a web page) about you and/or your book. You could actually set up one lens (page) about you and another about your book. Read Seth's post to find out some of the things you can do with a Squidoo lens.
Finally, go over to Fickr to post some photos of you, your book, you at a booksigning, etc. With a Squidoo lens, you can have your blog syndicated on the page along with your Flickr photos, plus whatever else you want to post to the page.
Again, read Seth's post to get a good idea how to go about all this.
