I think most bloggers are aware of the concept of tagging. You can label a post or "tag" it with a keyword. If everyone tags their posts about NECC, for example, with the tag necc or necc2006 as suggested by David Warlick, all of the posts from various authors will be collected in the blog search engine Technorati. Click here to see the results of all blogs tagged necc. This list should be growing and changing as the National Educational Computing Conference draws near.
I'm sure this has been mentioned elsewhere, but blogs are not the only things that can be tagged. You can also upload photos at Flickr and tag them as well. Here are some photos I took, for instance, at the Illinois Technology Conference for Educators posted under the tag iltce. If you search Flickr using the tag iltce, you will also find pictures taken by Tim Lauer and David Warlick. So once again, you can have multiple perspectives... this time via photos.... collected in one place. Flickr pictures will also show up in Technorati.
It doesn't stop there! If you use the social bookmarking tool Furl, you can create a category for your bookmarks that serves as a tag. If I bookmark web sites and put them into categories I created in my account (necc and necc2006), these web sites will also appear in the Technorati aggregate of everything tagged necc. Scroll down to the bottom of this page and you will see links submitted by under my username elemenous. I plan to bookmark interesting web sites mentioned during the conference in Furl. Conferences are great providers of resources and I'll be passing them on via my Furl account. If you want to see all of my Furled bookmarks, click here. If you want just to see only bookmarks I have in my NECC category, click here. Remember that as the weeks go by, these lists will be changing. Furl is also handy in that you can rate sites and add notes, which I rarely do. Maybe I'll start doing this at NECC!
By the way, I am sure you can do virtually the same thing with another popular social bookmarking service called del.icio.us. I just happen to prefer Furl. If you are a fan of both Furl and del.icio.us, try this bookmarklet creation tool. A bookmarklet is a little doodad that you install in the bookmarks bar of your browser. Every time you visit a web page and you want to record its url in a social bookmarking service like Furl or del.icio.us, you just click on this tool. It's bookmarking on the fly and on the web! So, if you'd like to use BOTH Furl or del.icio.us, you can create a bookmarklet that will allow to bookmark to both places with one click. Give yourself a pat on the back if you fully comprehend what I just wrote, but try it playing around with this stuff. It's really, really powerful.
