This was made using only the first page of the WSO forum at 11:00 PM Central Time. Made this by copying the text on the page, cleaning it up a bit, and pasting it into a free tool I came across- Wordle.
This tool lets you make a word cloud by inputting a bunch of text, an rss feed, or even del.isio.us tags by username.
If you're anything like me, you'll start thinking of a ton of ways you can use this tool! For this example, it's great for WSO creators and promoters to see what topics people are covering at the moment. (which indicates these are hot topics!)
I'll also be using this tool for my blog and probably use it for products I create when the situation arises. What about you, what could you use this for?
