The Dharma Overground provides a forum for hardcore meditators, and has refreshingly less dogma than most Buddhist sites I've run across. I liked Dan Ingram's view of things once he had begun looking for a path, where after a lot of searching, he realized "those darn Buddhists have come up with very simple techniques that lead directly to remarkable results if you follow instructions and get the dose high enough." He has a fairly no-bullshit guide to Buddhism, the MCTB, Mastering the Core Teachings of the Buddha. Dan also has a site, Interactive Buddha.
Also by way of the Dharma Overground, I found the brief but informative A Reformed Slacker's Guide to Stream-Entry by Tarin Greco.
Also came across Shinzen Young, who provides some dogma-free stuff, with his Basic Mindfulness Home Practice Program. Kind of like Kabat-Zinn for hardcore practitioners that want to go beyond simple MBSR. I was a bit put off at first by the new jargon he introduces, but ultimately I like what he's doing. It seems to be a noting practice, rather than a concentration practice.
