One of my reasons for starting my street review guide was to celebrate the minutiae of life. To highlight the little things that people accidentally miss, deliberately ignore, take for granted or consider not worthy of comment. I've been on the lookout for others with a similar mindset. Here is some of what I've found (Health warning: some of the following may not be suitable for nerd-allergy sufferers)
10,000 Birds (yes, ornithology, in case you were worried)
A Nice Cup of Tea and a Sit Down (Reviews of all things biscuity)
Bog Blog (yes, really)Boring Postcards
Cupcakes Take the Cake (I know someone who'll like that one!). And also Blognut (all about doughnuts)
History of the Button ("Tracing the history of interaction design through the history of the button, from flashlights to websites and beyond.")
Literally, A Web Log
London Review of Breakfasts
Smells of the Day
It takes a certain type of person to devote themselves to recording such things. I'm not sure what sort of person that is, but I had assumed that I was one of them. Having said that, it seems my focus is positively broad and unspecialised compared to some! Here's to all those who care!
PS. I should also namecheck Grow a Brain who/which(?) I found by Googling 'unusual blogs' and pinched a couple of these sites from their archives.
