Another gem from Phil Bradley’s blog (I don’t know where Phil finds these sites!). You put in your search strategy and then BananaSlug adds a random search term. Alternatively you can select a category for your random word – e.g. animals, great ideas, random number, themes from Shakespeare.
The idea behind this site is to promote serendipitous surfing. By adding a random term, which may or may not be relevant, you pull up pages that are buried way down in the results list and which you would probably never see. Sometimes it works, sometimes it doesn’t.
BananaSlug uses the Google APIs and is limited to 1000 queries a day. If the site is past the limit, you are diverted to Google with your search term and random word.
