There are less than 40 three letter word domains names available now. http://andio.herokuapp.com

$20 for the results of bash one-liner? (by my count there are far more than 40 left)

    for i in `egrep '^[a-z]{3}$' /usr/share/dict/words`
    do
      whois $i.io | grep -q '\- Available' && echo $i.io
    done

Heck, there's still a few two-letter .io domains left

    for i in {a..z}{a..z}.io
    do
      whois $i | grep -q '\- Available' && echo $i
    done

    iz.io
    jy.io
    kf.io
    kq.io
    lq.io
    qf.io
    qg.io
    qj.io
    qo.io
    qs.io
    qy.io
    uj.io
    yd.io
    yl.io
    yz.io

But, yeah, I agree, .io choices are getting a little thinner than they used to be.

Yes, $20 for you is too much, but there are lots of people who have no idea how to do a bash one-liner (me being one of them actually).

I worked on this project a while back and posted the list for free for over a year, not sure why it's a sin to charge money for it now.

Selling the remaining list is quite a smart idea. it obviously has value even though it would be relatively simple to figure out the remaining free domains on your own.

True, the task is not very difficult if you have a list of words to check against. If you're time to create your own list takes more than $19 of your time then its probably of some value to just buy mine :)
