A better way to use datasheets than old-fashioned paper and pdf documents lying around? Hack Your Datasheets Using Datasheet.net article tells about a new service to view, snip, annotate and share information from millions of datasheets with engineers around the world.

The biggest feature the datasheet.net service brings to the table, the ability to create “snippets” from datasheets by clicking and dragging the area you’d like to save. You can even get a public link to the snippet. I tried the service quickly and found it something that could be useful. Seems to be worth to sign-up.
