certain swells are worth being talked about.
when the analysis is educated and the subject deserves legitimate discussion, then what's the problem? certain factors like swell direction and wind direction that aren't always accurate on this or any other site (SW swells for nj and sea breezes) don't always get factored into the forecast.
on the other hand, if the post is like, "duhhh, is it gunna b gud tmrow?", it should be deleted.
