The site should be quick and easy to use - no long waits downloading huge graphics or staff photographs. Navigation should be simple. The site should be free of boredom and hassle. We think our site has the human touch. We don't download huge wordlists from somewhere on the Web, use a computer to find synonyms for each word as clues and then automatically publish what comes out without further consideration or editing.
Some people do.
We don't do it because it can also be nasty. It produces weird random words and often even stranger clues, sometimes offensive, sometimes duplicates of others. The results are usually, well, rather odd and not particularly satisfying to solve. We run this site as a free service. There are, however, some costs to it, not least of which is keeping Tetrarch, our puzzles compiler, fed and watered.
