Google Sites is great for sharing information in a professional-looking way at no cost. As with Groups and Docs, the site owner can customize privacy settings so that the site is public, private, or viewable by a list of designated users. You can also specify who can edit your workspace by inviting others to be owners, collaborators, or viewers. The “File Cabinet” is an online place to store and share files. Use the “Insert” feature to embed all types of content on the site, including videos, calendars, documents, spreadsheets, photo slideshows, and gadgets.
If your goal, however, is to build an online community for members of your organization, Google Sites is not as robust as Google Groups. While you can create a page about an individual (e.g., an online resume), Google Sites does not have a designated “member profiles” feature. Additionally, there’s no discussion board. You can post announcements for site viewers, but this feature is more of a one-way communication tool. Users cannot comment or respond to the announcements on the site.
