At most, it is a reliable source of advice for women who want to improve their chances with the opposite sex.
A post I made about why women shouldn't take the initiative in relationships evoked some questions about how to deal with shy men - after all, shy men don't chase women, and are unlikely to initiate anything.
That offense will reflect negatively on you and the relationship.
So be careful about how much (and which) initiative you take.
So whatever you would normally do to indicate your interest to a confident man, double or triple it for a shy man (in proportion to his shyness): While I don't suggest that you overtly ask out a shy guy on an "official" date (this would too flagrantly undermine what he knows to be his role as described above), I do suggest that you suggest and then ask him to hang out under casual pretenses.
Comments like "Oh, I thought you were going drive/get the tickets/plan the trip/[insert other traditionally masculine roles here]" can help in priming his confidence if it seems to be lagging and it bothers you.
Dating a shy man takes a lot of initial investment for an uncertain outcome.
Once this happens, you will need to gradually assume a less assertive (more traditionally female) role, because he will then be more liable to get bored with you, wonder if he could do better, consider his other options (the perception of which his newly-found confidence will likely inflate), fool around, etc.
The second caveat is that even a shy man has pride.
