As a military member who works with and utilized classified information, I'm somewhat concerned about the use of Web 2.0 tools. As mentioned in the article, the fact that information can be edited after posting by a different user leads me to believe that there's a lot of room for error. When actionable intelligence is posted, it needs to be very clearly differentiated between what is a known fact and what is an analysis. If the intel community can make these differences clear, then web 2.0 would be incredibly beneficial.
One of the problems that is often encountered when looking through intelligence is sifting through what is applicable. The same problems exist as exist when searching for something with google or yahoo. If you want to look up something as simple as how to grill a burger, you have to be very specific when searching or else you wind up with alot of extra, unnecessary information. If Web 2.0 can help the user who maybe doesn't work with the system every day have an easier process for finding exactly what they need, it would definitely be a large help.
Use of RSS feeds specifically could help increase communication, which can be especially difficult in more secure areas. You can’t just pick up the phone and chat with other individuals at time, so easier access to group information should simplify the process. The intelligence community will just have to be very careful about overwhelming people with extra info!
