One of the websites we regularly bookmark went down the other day, and we immediately thought of Diigo's snapshots and looked for the articles. Unfortunately although the snapshot is listed and "Grabbed by Diigo robot" indicates a date, all the snapshots are just blank pages. See http://tinypic.com/r/zsqrya/3 This is a major bummer, since this was one of the main reasons we started using Diigo rather than saving pages to our computers.
That is great, it is working much better. The good thing is that it doesn't even need a sign-in to see the page, although I do find the frame that Diigo places over the page to be a little too large and imposing. Maybe it could be a sidebar rather than taking up half the horizontal space. As it is you can hardly see and of the article and it is confusing which part is Diigo and which part is the page.
