When I first started getting serious about genealogy research, I loved RootsWeb. It provided surname and location message boards, a place to post your family tree data for free and even provided a large amount of disk space available for genealogy-related web pages. Best of all, it was free!
Then Ancestry bought Rootsweb. They assured us that nothing would change in the way Rootsweb was run. I never noticed any problems but was always wary because I just have never trusted Ancestry to do the right thing. This is only my personal opinion. It is not based on anything that has gone on in the past. I just always thought their share holders were more important than doing the right thing.
