thx, Sam. Here is a video from Matt Cutts: https://www.youtube.com/watch?v=UpK1VGJN4XY - it appears Google is OK with hidden text that makes sense for user.
For my site I have a lot of read more types like here:
http://www.honoluluhi5.com/oahu-condos/
http://www.honoluluhi5.com/oahu/honolulu-city-real-estate/
As you can see from those 2 links, I have created with only the user in mind and nothing else. In order to play it safe, maybe I should just show all the text somehow, even though it compromises user experience.
