I spend an enormous amount of time browsing the web looking for new ideas to write about, so one of the biggest problems for me is tagging articles for more careful reading later.The solution to this problem is to have a good mechanism for tagging a page as "to be read", and then be able to easily retrieve them at a later date. We've already written about using del.icio.us for this purpose, but I've come across the Read it Later extension for Firefox that has very similar functionality.
