Update: Wordle is back online!
I just learned from Larry Ferlazzo that Wordle has gone offline indefinitely. A visit to Wordle.net reveals this message from the site’s owner:
I am seeking pro bono legal advice, to evaluate a trademark claim against my use of the word “Wordle” for this web site. If you’re an intellectual property lawyer, with expertise in trademark law, and you wish to offer professional advice on this matter, please contact me.
Until Wordle returns, you might want to try Word It Out which I reviewed earlier this month.
On a related note, Remix America has been down for nearly a month. My emails to them regarding the status of the service have been unanswered.
