I'd like to welcome those of you who discovered my site because of the great article today at Lifehacker.com on how to get better at crosswords. The article, by A A Newton, has many excellent tips, like doing puzzles everyday, knowing when to cheat, and reading crossword blogs. The article also linked to this site, encouraging people to brush up on their crosswordese.
The one thing I would add to the article would be to encourage people to make crosswords a social activity. Get together with others and work on crosswords during a coffee break. It's a fun way to get to know your friends better as you interact over a puzzle. And you all learn from each other as you discuss the clues.
