Anyone who has worked on making detailed sites knows of the trouble that it can be. Creating HTML and CSS pages that are seamless and work on all browsers with no glitches can be tough. Making sure that you have the right content and working with the right style templates is a huge advantage, but for those who want to step it up even one more notch working with a shortcut and aid like WordPress is a wise investment of time.
Theme Sites. These are of course thematic, which will be helpful on what theme you want to use in a page. Scrapbooking is like Wordpress. If you are making a website powered by Wordpress, you will look for nice themes that you can work on instead creating your own. It should be appropriate in the long run as you post and update it. In scrapbooking, templates will stick for a long time after some time of adding all the elements, and it will be the basis of the overall look that you can't change. Photo Sharing Sites. These sites are both theme and group sites at the same time. Photo sharing is mostly their goal, but I have seen scrappers post their layouts or projects. So you will get templates or their ideas as well.
