This is a little tutorial for you guys, hope you appreciate it, I will try my best to explain it
Ok so this is all about using search engines as tools. For this our example will be "Science".
Now we are going to go to google and type:
site:.edu inurl:Science "leave a comment" -"comments closed" -"you must be logged in to comment"
Now what this does is find sites which have a .edu extention with the word science in the domain name as well as anything with leave a comment on the page
Now theres another way to do this so that you don't have to have science in the domain
now every page with those keywords will show up tooCode:site:.edu "leave a comment" -"comments closed" -"you must be logged in to comment" "Keyword 1" "Keyword 2"
Now think smart, don't go onto a science website and talk about tomato's. Make genuine comments and they will be approved quicker
