Seriously - that kid is f-in' adorable. :) Must go check out Flickr.

As far as f-locking things: I've f-locked everything because someone tracked me down here who knew me though a volunteer group (the only reason she knew my username here was likely due to the email account I used to be in the loop with that group). I wasn't comfortable with her reading my journal because I didn't know her well, and because a coworker was on that volunteer board as well, and that was a little too close for comfort. I didn't want to give up this journal, and really, the people who mattered were already friended here (provided they were on LJ in the first place), so it wasn't a huge deal.

I might suggest starting a second journal (one on something like wordpress.com instead of a more "immature" site like LJ) or simply start using the notes function on Facebook for your more academic pursuits. (Facebook would allow more networking and a more "professional" front, and you've already got that set up, and can filter quite a bit on there, if you don't want pics of Xander to be public to everyone and all that.) It means maintaining two places, but I'm a believer in keeping personal and professional separate to a degree. I rant here in ways I never would on something like Facebook, and I keep my personal details very sparse on my other blog. On my main website, at the moment anyway, it's purely professional (press releases, portfolio, etc.) because I don't want people looking to hire me to see my photos and such (even though there's nothing online I'd consider inappropriate).

Did that make sense? I think so. It might be clearer in my head than in my typing. :)
