If I remember correctly, this was presented at A2NewTech [ http://www.a2newtech.org/ ] a few months back (I don't remember which month). They had a good demo and I really like what they're trying to do.

I wish there was a little bit of a better way to do side by side comparisons between Google Street View and the submitted photos. I'd prefer some sort of side by side vew than the fade in/out method it has right now. I'm not sure I have any ideas on how to make that better, for now.

E.g.: http://whatwasthere.com/browse.aspx#!/ll/42.278652,-83.73908...

Great job guys!

I remember seeing this in the demo pit at Google I/O and thinking it was one of the coolest things I saw there, because I love browsing historic pictures.

I then promptly forgot the name of the service so thank you for posting this. Now I'm going to go waste the rest of the night going through pictures here.

Love the concept and execution. Manually cross referencing "Then and Now" pictures from the Denver Library of Congress made history tangible and finally interesting for me.

Neat!

I'm working on something similar but with business listings. Currently has some initial data for San Francisco and I'm working to add more.

"Years: 1995.0, 1996.0, 1997.0" Awkward data presentation or are you planning an 'interesting' way of specifying something like May 1995 as 1995.5?

Ack, no, just using the wrong format string. Will fix it soon, thanks.

Very nice cool site, good execution. Also impressed that this was built with ASP

I wonder if they're interested in local partners. I know a few people who've been thinking about doing this in Hawaii.

This is very, very cool. Is it your project?
