One of the reasons that the Bootstrapper Breakfasts have been helpful to bring teams together is that it's a low key way to have a serious conversation with one or more potential cofounders and form an impression based on more than a paragraph or two on a "dating site."<p>From folks who have attended a Startup Weekend or similar event, I hear that it's a good way to learn how someone performs under at least a moderate amount of pressure.<p>I am less sanguine about "dating site" although a lot of folks have contributed to the spreadsheet so it will probably help potential co-founders become aware of each other.<p>I also think you can form a reasonable impression of someone from reading their blog and HN comments but not everyone who has the strengths you will need to get startup off the ground is necessarily interested in contributing to a forum.
