F# is a wonderful language, albeit I'm still getting used to style.
Is anyone here using F# for real project? It would be great to see it in wild.

I'd show mine but you wouldn't see any code! My latest is http://newspaper23.com
I use F# to generate static pages. This allows me to completely decouple the back-end from the display. I don't have interactivity yet, but I really don't see a need to add a framework to get it. F# and mono allows me to shoot for brutal simplicity. I like that. Many times projects that might be huge monstrocities in other languages turn out to be just a few well-coded modules running as Unix-y microservices in F#.
People are starting to give F# a lot of love as a .NET language, then wondering "Where's the framework?" I'm coming around to the conclusion that it works best when there is no framework. Fun times ahead.
Yes, in F# and other ML-like languages you tend to use libraries more than frameworks.
(I'm the original poster, and I've been extolling the virtues of ML-style functional programming throughout this thread, but I still owe you an email explaining why I think OOP is ultimately better than FP)
Side projects have mostly been stats/data based: using type providers to mash together different data sources, with visualization via FSharp.Charting.
I've also used it in network indexing, processing 5TB of SIP signalling a day on a single server, then indexing and storing each packet for later searching. This is now used in the voice arm of a large public telco to provide troubleshooting.
F# is a joy to work with and every time I use C# it's annoying.
Actually, the biggest issue is mono-service. Since we run cross platform, we used the Windows service API instead of writing a normal daemon. This has been a source of "random" issues with getting it to start. But that's just our fault for not changing 10 lines of code and just running it like every other Linux daemon. Similarly, some code depended on file locking (because FreeSWITCH's CDR writers don't properly write to files) which doesn't work on any popular Linux file systems. There are probably some other little issues where we made a dumb Windows only assumption.
All in all, it's been smooth sailing. Stuff just works. We develop and test exclusively on Windows, then deploy the binaries to Linux. I can't say enough good things about F# and about Mono.
Also, I don't use it on Linux, but F# Interactive would only work on some installs. A problem with readline iirc. I'd guess that developing on Linux will be more rocky than using Visual Studio.
