Because here at XMarks we are amongst friends. We may not be able to meet them at the local coffee shop because they live a hundred miles away, a thousand mile away or an ocean away. We all have a common topic of discussion - kilts. It is how we met, it is what we (mostly) wish to discuss. Sure we talk about frivolous things, as you've suggested, along with current events, suggestions, ideas or a Victorian tale of high adventure. There are post that we are not interested in reading but we're free to skip over them if we choose. Hey sometimes we argue (let's call it debate) about the same old thing, just with new voices with new views. We different because we choose to wear kilts, we come to learn whether this goes with that, occasionally we learn, mostly we laugh. We post to socialize, because we are amongst friends.
