What He Said: GDN Shortcomings
Craig Andera has it exactly 103% correct when he lists the issues with GDN Workspaces. It's great that Microsoft provides them, gratis--at the same time, SF is free and it's better to boot.
Thinking about working with .Text when it was on GDN versus working with it now on the generously provided vaultpub--it makes me want to buy Eric Sink some fresh-hewn flowers or something (actually, what it really does is make me want to convince the pointy-heads-that-be at the monolithic day job that it's really all that and a bag of commits, and that we're bigger idiots than I already know us to be for not running to it as our distributed source control standard for enterprise MS development projects... so I think Eric's a little shrewder than he lets on in his MSDN articles[1])[2].
But yeah, I'd rather watch Murder She Wrote than use GDN workspaces until they can overhaul them completely. Here's a notion: save the time and effort, just contract SourceGear to run a 50-server Vault farm at vault.microsoft.com. It's nearly that easy of a fix, all it takes is billions of dollars in cash.
