You know how you can tell?
Because every time Flickr comes out with a new feature, your favorite blogs begin to look like they've been hit by the local overpass graffiti artist.
That's because Stewart is very smart and geeky and businessy and creative and he doesn't slow down. He leaves ideas scattered behind him in chalk outlines that are no longer just "inside" flickr. They're spreading. Look out.
Now you can check out photos on flickr, and with just a click-a-da-mousey, share them with your blog readers, complete with your witty commentary.
Stewart's announcing a new partnership over on his blog too.
Ah Stewart. What next, you crazy kids?
