I use Flickr for sharing miscellanious mostly single photos + uploads from my mobile.

Full sets and most of my other photos are stored and displayed at my Picasa Web Albums (which allows super-easy uploads AND even more easier downloads for family and friends).

I post some of my photos to Panoramio.

My public photos are mostly "public scenes" (urban, rural, nature). Photos of friends & family are limited to those on my friend / family list(s). So friends, add me as a contact if you want to see them.
