If I read you correctly, you upload all your pictures to Flickr automatically? Can you explain more about how that works?

For a few years now, I've been putting photos on Flickr. Usually, I use the Flickr Uploadr which makes it easy to move photos from my computer to the site. Eye-fi makes it automatic - it goes right from the camera to Flickr - no computer involved. You lose some options, but it works.

is Flickr your 'source' location for all your photos or do you also keep local copies?

I keep local copies on my computer (or external hardrive). The photos that appear on Flickr, for the most part, are ones I want to share or archive. I have over 14,000 photos on Flickr. Thank goodness for tags. :)

do you resize your photos prior to uploading. If so, is there an automatic way to do this?

Using Flickr's upload tools, you can have them resized as a batch if you prefer. However, I think it's a good idea to archive them in large format if you plan to use them in the future - with a "pro" account storage is unlimited. Also, Flickr recently integrated Picnik online photo editing that enables you to resize photos via Flickr.

Hope this helps! We've got some photo-related video-goodness coming out very soon!
