I don't find it ironic. I find it unrelated. If you could find a successful startup today that used a lot of IBM technology -- even if you could show that a startup today succeeded only because they were using IBM technology -- that wouldn't turn IBM back into the dangerous monopolist it once was (which was what Paul's article was about).
Another startup that just caught Techcrunch attention (and apparently got financed because the company has a real business model) is Gigya (http://www.gigya.com/) and they, too, are using Microsoft/IIS 6.0.
I'm not saying that there's a strong correlation between Microsoft and your success rate, but I just find it ironic.
The rest startups seem to not to have their business models and hoping for a buyout. Actually that includes Reddit as well. If you read Aaron's blog and see how they're desperate to get a "deal" from PG.
Note: I assume Microsoft/IIS 6.0 = ASP.NET
