It's a website, it's a blog, being able to write is unnecessary, and browsing is rewarded.
Tastespotting is the most simple concept that's more rooted (we're told) in porn than foodblogging, but and it totally works.
The people who brought you the beautifully-done web 2.0 lovin NOTCOT (LA designers Jean Aw and Daniel Frysinger) joined forces with Friend-of-LAist Sarah of Delicious Life to create a blog that allows the user to sign up, find a cool image of something food-related and post it along with a short caption.
Simple. Beautiful. Elegant.
Addictive.
