Martin Fowlers opinion on architects ;)
Writing about web page http://www.martinfowler.com/ieeeSoftware/whoNeedsArchitect.pdf
Just read an excellent article on the "architect" role and why it is abiguous, uneeded and can actually lead to a dangerous lay of responsibility.
Have a read :)
I really liked the idea of not having an architect, but having a team "guide". I also really like the idea that as the guides responsibility is to impart knowledge/mentor the team, that the value of the guide is inverse to extent to which they are a bottleneck. In other words, a guide should be working themselves out of a job by mentoring others to take over :)
