The Folly of Volunteering

I need to tone down my enthusiasm. I often find that I link to a site, promote it in forums, recommend it to friends--all for free naturally--and then sometime later, the site changes policy and jabs a thorn in my side (userstyles), or deletes my account without warning (project honeypot), or goes down for good (the 'tree). I have no luck with my recommendations AT ALL. I have no luck with volunteering my time or talents. Usually when I volunteer, I wind up in the end feeling like a fool. I think the best thing to recommend is a dead author. That way, one will never be disappointed.
