More ideas:

 - What's on your To Do List?
 - What kind of records on your Research Map are marked "Here Be Dragons"?
 - What are some of your "wow" records (that you were really excited to find)?
 - If I Were Dictator:  things I would change about online genealogy sites 

 
I'd also like to see a series of hosted discussions (not necessarily part of the weekly chat) on technical topics.  For instance -- last weekend while I was hanging out in chat and working in another window, I did a Google search on persona records and ended up reading a lot of blog posts and forum discussions written by participants here on G&FH.se.  Could we do something like a Reddit Ask Me Anything where a volunteer makes him/herself available for questions?  The software developers could sound off about their software, I could talk about how my linguistics experience has informed my family history research, and so on.  Obviously a person couldn't hang out the entire 24 hour chat window but they could be there for a few hours, and people could leave questions which could be answered later as time permitted.  I think the Reddit AMAs are a couple of hours.
