Are they paying attention?

This blog post is basically an open-ended question.  Do other, bigger paper & pencil RPGs (including their audience, fans, players, GMs, and scene in general) even know about the OSR?  And here's my followup question: If they know about it, do they care, do they use it, do they buy our products or use our free resources, are we influencing them at all?

Ok, here's a post-followup question I came with after discussing it a bit with +As If and +Erik Tenkar:  I assume that certain OSR blogs, podcasts, products, resources, etc. permeate the RPG mainstream from time to time, despite their niche within a niche status.  Does that increase awareness of the OSR as a whole or is it merely limited to the stuff that has managed to break out of the OSR ghetto?

I believe the OSR effectively changed 5th edition for the better, but what about the average D&D 5e gamer?  Are they aware that the OSR exists?  But specifically, I'm wondering about Pathfinder, Dragon Age, Numenera, Dungeon World, 13th Age, Fate, Savage Worlds, and other popular titles I can't think of right now.  Call of Cthulhu?  World of Darkness?  Post apocalypse RPGs?

Since mostly OSR people will probably see, read, and comment on this post, let me know what you've experienced.  If anyone actively into the above RPGs but not the OSR actually stumbles upon this, please answer as best you can.

Thanks,
