Group Sites or Social Network Sites. There are usually dedicated sites for different groups depending on what they are doing. Social Networks are much broader, but groups within them like scrapmoms, scrapsisters, and so many more usually share their ideas and projects. It is up to you whether you will join any group if you want to get more details and interact with the people within the group, but you will get templates in there.
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.
