I blog on www.blipfoto.com/dogwithnobrain
I started on this site, in february last year. Rules are, One Photograph, per day! It can be about your photography, it can be about your writing, but It's a disciplined approach to keeping a log.
I hit 500 blips yesterday! I couldn't believe it! My blip has had 320 hits, and I've accumulated 125 comments over the courseof yesterday and today!
For years i've tried to keep a diary - you can see here, I come and go, but with the exception of one day, and it was excusable, I've blipped every single day. Wow!
