1. Gallery is a wonderful, robust open-source platform for hosting and sharing photographs on a personal website. Unfortunately, the larger the database gets the slower it runs. The interface, while infinitely customizable, isn’t particularly user-friendly (an aside: the beta for 3.0 looks very promising, and I would encourage others to give it a try). Flickr exists to host and transfer tremendous amounts of data to users quickly.
2. The social networking aspects of Flickr are unparalleled and steadily growing. Flickr can be seamlessly woven into dozens of applications and services — and where a gap exists, an API sits ready.
3. The community at Flickr. As I connect with others and add contacts, I am committing myself to a community that encourages sharing and networking. Hosted here, I am only responsible to myself. Two years passed as I delayed uploading photos from my trips to Europe. With a firm deadline and the knowledge that people will be actively viewing new images, I pushed through and finally finished what I started.
4. A simple, transparent method for implementing Creative Commons licensing.

The first attempt at integration with this site will be via the Flickr Gallery plugin by Dan Coulter. There seems to be quite a few options out of the box, but it also looks to have excellent support for the Flickr API search method, which allows for a great deal of flexibility.

The existing albums at arcade will remain live indefinitely. I was less selective when posting photos to Gallery, so there may be value in the additional images that haven’t been migrated.
