docstoc is a great solution for teachers that want to post files online, but don't want the hassle of managing their own web site. teachers can post presentation files online for later review by students. posted files make great study guides or provide a solution for absent students.
final verdict.
docstoc is easy to use. it provides a great solution to users looking for a way to share documents, presentations, spreadsheets, or other files. it is free. docstoc provides a great solution for online distribution. this is not a good choice if you want to create living documents & online collaboration as users cannot edit online files without downloading. google docs is still the king of online collaboration, but it is not a common choice for classrooms due to its log in requirements (it's also blocked at some schools). check out docstoc.
