What's neat about Photobucket is that it allows you to upload photos, videos, and other animations for sharing over the web. For embedding images and videos, I think it's much easier than Flickr--the tools are more like YouTube's. Though there doesn't seem to be a filter for searching--a few of the photos I saw when searching "dressage" were a bit sketchy.
Scrapblog is really fun and cool. I made a quick scrapblog:
I like that it costs nothing, looks great, very easy, doesn't make a mess like real scrapbooking. However, it doesn't look like you can print your pages, which doesn't make a heck of a lot of sense to me. Still, the templates are stunning, and it's got all the web 2.0 social tools like sharing, embedding, and RSS feeds.
