I've known about Flickr for some time.  It's touted as a great Web 2.0 site with all the Ajax trimmings.  I tinker and sign up for websites all the time with no other purpose than to just try it out.  I never did so with Flickr.  Whether it was because I don't take that many pictures, Picasa seemed to do the same thing, or the fact that my snapshots seemed outclassed by some of the photos already I don't know.

There's also some pretty neat research stuff going on with Flickr and tagging, the coolest I've heard of lately is PhotoSynth from Microsoft (check out the neat video from the TED Conference).

I signed up for an account and uploaded pictures after wanting to upload some pictures of my new son Lincoln.  The computer I was on was a "rental" from the hospital and was severly limiting.  I used Flickr to upload and resize the pictures automatically.

Geoffrey A. Moore wrote in his book Crossing the Chasm (Google Book) regarding technology

• the first 2.5% of the adopters are the "innovators"

• the next 13.5% of the adopters are the "early adopters"

• the next 34% of the adopters are the "early majority"

• the next 34% of the adopters are the "late majority"

• the last 16% of the adopters are the "laggards"

When it comes to photos I'm clearly in the "Customers want solutions and convenience" group.  Now that I've found Flickr, I think I'm on Flickr to stay.  It's free, it's Yahoo owned and therefore very reliable and very responsive.  The Ajaxy goodness is nice and very cool, but the Ajax is really just a means to an end.  The actual things I want to do with my photos once uploaded have already been thought of and are provided through a quick, reactive drop down.  Very slick Flickr! Thumbs up to you guys and thanks for helping me out of a bind.
