Applications no longer consist of the singular "web page" but come in many publishable applications such as "white papers" (policy papers), reports, journal articles, graphic organizers, and PowerPoints (all published on web pages), web page construction itself, and wikis, to name a few forms of online writing.
WIKIS: There are several sites which provide free templates for creating a Wiki. These allow students to collaborate online and create group-writing projects. The Wiki pictured below linked to pages on which students collaboratively defined specialized terms and posted "brainstorms" for their class projects:

This Wiki itself is a collaborative venture for our conference presentation on writing in Web 2.0. Like the class, it is constructed in the "Wetpaint" application, which provides templates as well as basic editing and uploading features. As shown below, the editing bar allows you to adjust the text, add links and photos, and save your edits.

Web pages: GOOGLE SITESVisit
sites.google.com and look at the video on starting a google site. Then, sign up! You can add students to your site, have students set up their own sites, or your college can create a domain name as well, which organizes student contributions in one site manager.
