Comment Hey, we get badges! (Score 1) 131
At $DAYJOB, we've had a variety of work collaboration tools over the years similar to the then-current* social networking tools. The most useful ones are instant messaging and wikis (or wiki-equivalents), and internal Usenet groups back in the day. Apparently having little badges next to your name is something that some current social networks do, so ours has that also (I haven't used it; I suspect there's some sort of "VMware User - Achievement Unlocked!" sort of thing.)
And we do have games, like "Guess which Wiki pages are current or abandoned!" and "Guess which User Stories in Rally are current vs. long-irrelevant!" (If you win the latter one, you get to submit your own user stories under the ones the Scrum Master is going to reject for this sprint, instead of under the ones he's not even going to look at.)
I will post a less-cynical note elsewhere in this discussion
* ok, actually similar to the then-slightly-out-of-date social networking fads, rather than the actually current ones...
