When offline for more than a couple of days, I will indicate this by [brackets] in my moniker. I will eventually read and respond to all your comments!

I post pictures mostly for public view and enjoyment, but also for my own education in photography (where I know I have lots to learn!). Several of my photos are tagged critique welcome, and I mean it! Therefore, please add whatever brutally honest comments you like to whatever image you find in my photostream which carries this tag, but please explain what you don't like or why.

I am a radar scientist, and I started the group for Radars, radio telescopes etc., which features pictures of radars, radio telescopes, etc., basically anything involving radio waves and interesting antenna structures.

Thanks to the inspired genius of dr. loplop, I also started the group dedicated to pictures of somebody else's cat, which everbody is talking about these days. Given how critical feline presence is in the process of computing interestingless, this is perhaps not so strange.
