There's something undeniably significant about the first of anything. In this case, this blog is my first on this site, and that makes it significant as there will only be one first blog. Granted, there can only be one second blog, and one eleventh blog, but the fact that this seems irrelevant illustrates how significant firsts are, because it is relevant that this is the first blog. Or at least I think it is hence the mention. Perhaps you don't find anything about this being the first blog significant at all; it is only the first in relation to the others, and is alone no different from the others.

Either way, this is my first blog. More to follow.
