Just $1 can make a difference. Quizzle and the Quicken Loans family of companies are running a “tweet-a-thon” today (think telethon, but on Twitter) to raise $10,000 in 10 hours to fight ALS (Amyotrophic Lateral Sclerosis, aka Lou Gehrig’s Disease), a progressive and fatal neurodegenerative disease that affects nerve cells in the brain and spinal cord.

You can help the cause by donating just $1 at TweetForALS.com. If you’re on Twitter, lend us a hand by following @TweetForALS and tweeting us (using the @ reply) to let us and all your followers know:

I just donated $1 to @TweetForALS to help raise $10K in 10 hours for ALS! #tweetforals

The idea behind the tweet-a-thon is to use social media for social good. And you don’t have to be on Twitter to help. You can also spread the word on your MySpace or Facebook page, blog, forums and other online communities. Just refer your family, friends and network to www.tweetforals.com, where they can donate and find more information about ALS.
