This program is really meant for people of the class "I really want to use Microsoft products X, Y, and Z, but I can't, because I won't be able to afford licenses until my business has spun up. I'll make do with this opensource stuff instead." Now, I'm not entirely sure who these people are. Maybe they're developing desktop software or something. Provided they exist, though, this program could actually help them.
Personally, I use both MS and FOSS products extensively. I am a huge fan of Python and it is my primary scripting language, but my main career is as an MS SQL Server DBA, and I think that for many applications (not all) it compares quite favorably with mysql and oracle.
I think it's much more likely that they are trying to eliminate one reason new businesses/consultants may decide against using Microsoft tech (which their market research may have yielded). If they can make Microsoft tech accessible to startups, web dev agencies and solo web developers then that's a big step towards growing their dev popularity.
Looks more like a last straw to me.
There's simply nothing they could realistically offer at this point to lure the web community into their walled garden. Dozens of OSS stacks are competing for mindshare. Microsoft is not even playing.
EDIT: Also might be worth mentioning they use the BizSpark program.
I find the "Totals for Active Servers Across All Domains"-graph at the bottom especially intriguing.
Either Microsoft didn't pay their NetCraft-bill, or IIS is falling off a cliff here.
So, from what I can gather, Spolsky and Attwood are:
A) Out of their minds (possible?)
B) Are limited and going to have issues since it's built on the Microsoft stack.
Edit: Also, I didn't know if you knew SO was built on the Microsoft stack, I was asking a legitimate question.
I wouldn't say the two are out of their minds. "Misguided" is more polite, I guess.
In any case, I'm not arguing with you on the popularity of the two for sure, but I am happy MS is deciding to get their act together and really try to compete, however slow and small their steps are.
Edit: Okay you got me curious, why was this down modded? Was it outside the scope of the conversation? Or was it the comment about Spolsky and Attwood?
Until you can show that using the new Microsoft technology we are talking about (and MVC has only just come out) actually increases development time by a significant factor or some other significant problem, labelling it "improper tooling" is simply identity-based Microsoft hate.
