OpenStreetMap
I wonder if there's any place that has a list of places to check; I found a road at osm.org/edit?editor=remote&lat=42.14573&lon=-88.0402&zoom=15 that doesn't line up at all with the satellite imagery, and while I was thinking to go and check for myself, I was thinking it would be nice to have a centralized place where people can add a "hey, this might not be right" area.

usually, people add a 'fixme' tag to things they think should be fixed in the future. Ie, you add half a trail.
http://keepright.ipax.at shows fixme tags, as well as common mistakes such as errors caused by bad imports.
There are several quality tools out there. osm.wiki/Quality_Assurance
I think there's also a site which highlights 'unmodified tiger import' so people know to check tiger imported data (usually, the nodes don't connect to manually added roads, or are low resolution)

http://openstreetbugs.schokokeks.org/ - very useful tool to post "bug" markers. They can be seen after that in JOSM editor, also in Osmand navigation program. Sadly, AFAIK there is no history layer - after bug was closed it stays on map for a week, then dissapears without trace.

Those are great sites; it'd be good if there was some link from OSM to them directly, or put together something equivilant on the OSM site for others to use
