Want to listen in on the tweets from the most instructive people in the Agile community? Here’s where to find sage advice in 140 characters or less.
With only 24 hours in a day, you certainly can't follow every person on Twitter, or even all of the people who claim to be experts in Agile software development. What I provide below is meant to be a starting point.
This is not a list of Capital-A Agilists, at least, not strictly speaking a list of the best known people in the Agile community. No, I choose to make something a little bit different: a list of people worth listening to. The individuals I recommend here may have a decent following, may be a contrarian, or might just be an "undiscovered gem." Finally, some of the people are busy doing the work, leaving little time for self promotion. In that case, my preference is for people with a long view: the ones who have done "Agile" work, then stuck around for years to see the long-term consequences.
All that said, here's the kicker: For me to include someone for my list, the person has to actually talk about software in an interesting way that provides some value. Sure, every now and again these people might tweet about national events, finance, or what they had for breakfast, but the majority of the Twitter stream should be interesting ideas you can put to use.
Enough about the list; let's get to it. In no particular order ...
