Oh no Spangle I feel for you, I was gutted when my old Olympus was smashed & the same when I had the first new replacement stolen at the end of a day trip out for DDs birthday - card was full of irreplaceable photos - thankfully our insurance did cover the camera, but sadly photos lost forever :(
nice ideas on the Adele Enersen link, but a bit too twee for my personal taste, I prefer the likes of Robert Maplethorpe, & Hugo Platts landscape stuff
I vary a lot on my subject matter though, don't think I have any real theme, maybe photo journal would be a better description
as it just depends on what we are up to & what I see, I do like to take a lot when we travel anywhere, but that can be anything that gives a feel for where we are, & probably nature, I can take a lot of insect photos
Due to our old computer dying a while back I'm currently without photoshop & have (temporarily) lost all my albums :( so can't upload any photos ATM - & really missing my photoshop & seems I'm going to have to invest in the new one, as apparently the software on the old one just isn't compatible with out new computer, so where as I had sussed it all out - looks like I'm going to have to start again 
I do like play around with lighting on still life stuff, & tend keep photo records of stuff I make, I regret not doing that when I was younger, so do make a real effort to do that now - intend to put together a recipe book for DD when she's older so currently take a lot of foody ones - I've just remembered I actually already have a few of my pictures on my profile, but not my best ones
