Thomas,
I accept that this is the down side, however, the majority of blogs I aggregate from are really technical content only. For example, if you look at vfp/vb wishlists past and present, the ability to create WIN32 threads is a commonly recurring request. If you have no experience of threading/concurrency then go look at blogs such as Larry Osterman's
http://blogs.msdn.com/larryostermanyou will see that concurrency is not a trivial issue (even for him!) and he explains this in the context of MS technology (obviously) but from a purely technical standpoint. You begin to realise through his personal experience that maybe adding free threading to VFP is not such a hot idea? You learn a load of cool stuff that you really couldn't find that easily in MSDN.
BTW I am not pro/against free threading in VFP, I am just saying that independant blogging has opened up a whole wealth of personal knowledge.
Regards
Neil
