Bookmarklets
There are a couple of very useful bookmarklets on Scintilla's 'tips' page. The first - "Find in Scintilla" - is for when you've followed a link to read a story on the original site, or just ended up on a science blog post while wandering around the web, and want to get to that item on Scintilla in order to rate that story or recommend it to someone. Click the bookmarklet and if that item is found in Scintilla you'll be taken straight to it.
If the item unfortunately isn't found in Scintilla, it might be brand new and hasn't been indexed yet, or the source might not have been added to Scintilla. In the latter case, let us know and we'll look into adding the source as soon as possible.
The second bookmarklet takes the text you select on any web page and runs a "More Like This" analysis against Scintilla's index of blog posts and news items. This is a good way of quickly finding more items that discuss topics similar to the page you're currently reading.
