their tree gets large and unwieldy and they need pro tools to help work on it. (searching, merging, etc)
But with a 100 person limit for free trees, this is never going to happen.

I never expected to become a paid user. I never realized until I was 8,000 profiles into my family tree how truly awesome Geni is, and that's when I chose to become a lifetime member.
But if I had been limited to 100 people in my tree, I never would have even created an account. I recognize that Geni is probably struggling for cash, but that's the price of trying to win the race to critical mass. Geni has industry leading technology, and ability to become the wikipedia or facebook of genealogy, but not if you scare off every new user before they ever get to see how awesome the big tree is.

And the worst part. I have met relatives through the site, over 50 family group members with trees from 30 people to 14,000 who are all free users. They're now unable to continue without paying?
Really? You are actively halting progress on Geni's best asset, which is the big tree itself and collaboration.
