Some of my favorite articles, off the top of my head (and a bit of browsing) :

• A Fable of Science and Politics
• Explain, Worship, Ignore - I am, as of now, something of a naturalistic pantheist / pandeist; if you've heard Carl Sagan or Neil Degrasse Tyson speak on the wonder that is the existence of the universe, it's something like that. Unlike what is written in the linked article, however, I'm not convinced that the initial singularity, or whatever cause the Big Bang might have, can be explained by science. (Is it even meaningful to ask questions about what is outside the universe?)
• Belief in Belief
• Avoiding Your Belief's Real Weak Points
• The 'Outside the Box' Box - How much of my belief system is actually a result of my own thinking, as opposed to a result of culture, society, etc? Granted, sometimes collective wisdom is better than what one might come up with by oneself, but not always...

So, I found my introversion much easier to manage when I started scheduling time by myself to recharge, and scheduling infrequent social events to make sure I didn't get into too much of a cave. It had been easy to get overwhelmed with social events near each other if I didn't have something on my calendar reminding me "you'll want to read a book by yourself for a few hours before you go to another event." That sort of thing might be helpful to consider.

I have Meetup.com to organize and schedule social events, and of course there's the LW meetups. I get plenty of alone time, so that isn't really a problem for me. (Some minutes of thinking later) The particular issues aren't something I can accurately put into words, but they're something like 'active avoidance of (perceived) excessive attention or expectations, either positive or negative' and 'fear of exposing "personal" info I'd rather not share, and of any negative consequences that might result'. Perhaps not surprisingly, I greatly prefer internet or written "non-personal" communication over verbal communication.
