A while back BigKriss posted this link to see who is online. I use it regularly because I find interesting (to me at least) old threads (like the one on the 535 vs 525) that I would not otherwise find. I look at what the guests are searching for and that is how I stumble across interesting information.

For the last week I have noticed that 2 or 3 or 4 guests at a time are looking at profiles and often the profiles they are looking at are ones of people who are not currently active. Just now, I noticed that the two profiles they were looking at happen to be next to each other alphabetically.

I am not sure what information people could get or what use it could be put to, but I do think something is going on. Probably a good idea not have full birthdays or if you live in a small town, not to have the town.
