I'm frequently looking for a different way to phrase a word. For example, today I wanted to find a word similar to "plague" but without the negative connotations. If I type "thesaurus" into Google, I get
http://thesaurus.com which is very heavy on ads and hard to use
http://visualthesaurus.com which doesn't work without a plugin I don't want to install
http://www.merriam-webster.com which actually isn't a thesaurus and bombards me with flashing ads.
and many more of similar makeup
Maybe I am asking too much, but does anyone know of a thesaurus site with low ads, fast response, and high quality? I was hoping that Project Gutenberg's Roget's thesaurus might provide a solution but the number of words is rather low.

rel="nofollow"attribute applied to them, so they get no Google page rank from here when you link to them. If you link to them, it makes everyone else's lives a little easier, since we don't have to copy and paste to visit those websites... – ColdHawaiian Jun 19 '11 at 22:35
