Yesterday I first time heard of Imacros plugin for firefox. It's fast and easy to use. It's a script which helps to automate everything like form filling etc I had an idea to use it together with php. Php script could generate imacros script which would bookmark popular social bookmarking sites like digg, delicious and so on. All what you would need to do is enter your social bookmarking sites account info - username, password. also title, tags and description! So what do you say, is it worth to try to put it together ?
