i wish there was better ways.
Minimum filtration outside of my own preferences. This means forums that allow semi anonymous posting, IRC etc. You have to use external tools or learn to mentally filter though.
Finally, invest time in communuties that collect and share content, figure out your way around what is left of usenet and don't forget gopher and anonymous ftp servers.
Some YouTube content is really good but can be tough to find. Likewise with podcasts.
