Since we specifically discussed the Hacker News community, I thought it valuable and worthwhile to post here and see if the community had opinions on the topic and, perhaps, could share ways in which we could help overcome it.
My sense is that HN is generally filled with smart, open-minded people who love applying science and technology to marketing (or any other problem), yet SEO (and web marketing as a whole) seems to attract derision, often without context.
Love to hear your thoughts.

RE our specific situation: We're hiring primarily for folks to work on our web crawl, processing & machine learning platforms (as well as some front-end applications that plug into these systems). A good comparison would be Google's/Yahoo!'s/MS's teams in the early days working on 50 billion+ page indices, metric construction, crawling, serving, etc. We've heard that these are typically interesting, sexy problems, but that the "SEO" industry bias is working against us.
