I read a blog post yesterday with more information on what will be available to non-Ancestry.com subscribers who take the DNA test. It said they will get "matches" to other DNA users and be able to see a limited version of paid subscriber trees. Not sure yet what that will mean, or what non-paid (free) ancestry.com members now see, but I wondered if this will mean even more matches to "no tree" people? Anyone else have thoughts on this?

Addendum: ancestry.com's blog says they will see 7 generations of your tree (as you can now see if your match has a tree on ancestry.com)
