Diigo Diigo is a social bookmarking website which allows signed-up users to bookmark and tag web-pages. Additionally, it allows users to highlight any part of a webpage and attach sticky notes to specific highlights or to a whole page. These annotations can be kept private, shared with a group within Diigo or a special link forwarded to someone else. The name "Diigo" is an acronym from "Digest of Internet Information, Groups and Other stuff". Premium account holders can perform full-text searches of cached copies of bookmarks. A full-text search also searches page URLs, tags and annotations. This means that premium account holders can choose to omit tags that already appear in the text of a page to be bookmarked (although text inside images cannot be searched). The launch of Diigo met with mixed responses, from the unimpressed to the enthusiastic. Diigo beta was listed as one of the top ten research tools by CNET in 2006. Outside the website, Diigo's graphical user interface includes an optional bookmarklet, or a customizable toolbar, with various search capabilities. Highlight is enabled by a menu, that can either appear automatically when content is selected, or be embedded into the context menu. In March 2009, Diigo acquired web-clipping service Furl from Looksmart for an undisclosed price. The site also has an extension available on the Chrome Web Store .
Edmodo Design Edmodo's user interface has been described as similar to Facebook. [ Using Edmodo, teachers can post grades and assign homework to students. Students can then submit the homework and view their grade. The transmission is fast and paper-less. Teachers eliminate crossposting through the creation of sub-groups within a course. After each course period is completed the teacher closes out the network and creates a new one for the next course. Groups Groups are for a student's classes in Edmodo. Whenever a teacher posts to the group, it shows up as an alert in the notification box. Teachers and other students can also send you direct messages, and two newer of the newer features are quizzes made up of open-ended or multiple-choice questions and badges, which a teacher can assign to a student. Founders The founders of edmodo were Nicolas Borg and Jeff O'Hara.
