Welcome to the Q&A Forum

Hi Matt, To answer your question directly, yes you will see an SEO benefit from that in the form of brand recognition and potential referral traffic. As for ranking improvements though (what many wrongly define as "SEO Benefit"), no. You've already raised the biggest concern which is posting a link directly to your site which can have a very spammy feel to it. Particularly if you push too hard and actually start to spam, you run the risk of getting picked up by /r/hailcorporate which pretty much marks the death of your brand on Reddit! As with most things in SEO, if you're offering a truly valuable resource in the right way, there are only positives to be had from it, albeit indirect in this case.
