Personally I think there's just not enough widespread interest to make this a true community effort. While there may be hundreds or even a thousand or more people chasing any given event nowadays, it seems to me that only a small fraction do anything more than slap a quick picture of a picture they took of a tornado and say "oh yeah! I saw this today near soandsosville!" on FB or the Twit. Even fewer write detailed accounts of their adventures or include any post-mortem analysis of what they saw, when, and where they were when they saw it. Meteorological discussion is almost completely absent. Of those that write accounts, even fewer still place that sort of information in a location that would be expected to remain online for a long time (i.e., many use Stormtrack REPORTS threads to link to their Flickr, YouTube, or blog page), thus providing for the potential for a great amount of information to be lost unless it is archived in some sort of objective sense.
Since so few are willing to actually do the work of creating an archive, I figure any archive created would be inherently biased towards the experiences of those who make it. Above that, though, the record would simply be incomplete.
I don't think it's good enough to just ask chasers to contribute their information. Many chasers have other stuff to do with their lives - jobs, family, other hobbies, and just may not be interested enough to take the time to add significant material to an archive.
