In searching for nifty tools to use with my office cohorts, I came across two little browser plugins that offer a great feature- the ability to share notes and information on websites that I visit. 

The first one is www.trailfire.com. It allows you to add notes, pictures, and video to any webpage you visit. Anyone who has the plugin installed can see your notes (or you can set the notes to private or friends only). You can used the trailfire plugin to create a virtual tour of different sites, and users are prompted with page buttons to walk through your comments. I have a brief example of a tour everyone can see, covering some of the cool Web 2.0 companies that are here in Seattle. If you install the plugin, you can see how it works on a complete level.

Another similar service is www.bluedot.us. In many ways it operates like Trailfire, but it lacks the ability to group a series of ‘dots’ together. It does have some great functionality for creating a list of friends or coworkers (almost like myspace) and is very easy to use. 

Just to be completely fair.... there is also Amberjack, a service that doesn't require a plugin to operate. It lacks the ability to limit access to coworkers or clients, but has the ability to create custom skins that are unique to your needs. It is very simple to use and has a web based form for creating your tour.

Just imagine that you want to create a tour of ten homes in your office that are listed on different websites- You can use Trailfire to collect them all in a string, you can share a few notes on each property, and you can all add extra commentary as agents in your office (or clients) note things about certain properties.
