There are lots of sites coming up lately using popular company searches like google, wikipedia, technorati with some extra spice in it, be it integration of other service or just some fancy AJAX. I found these two websites which basically uses wikipedia. Well the service or say the search results are nothing but same as the usual wiki searches ;) .
BashR : Now as the website hompage states its “A web 2.0 project that bashes together Wikipedia, flickr and Delicious on millions of topics”. One positive feature maybe, it shows flickr photos and del.icio.us links tagged with the searched keyword.
WikiWax : WikiWax is something that searches wikipedia results in realtime with AJAX. Pretty sweet if you are newbie playing around with AJAX appz.
