I don't "keep front-paging my own nodes". I've done so twice. Ever.

Further, I didn't realize this was considered taboo. I operate on the logic that if a question looks interesting, instructive, and the problem is relatively generic enough to appeal to a broad audience, I front-page it. The last two times, these happened to be my own nodes.

In future, and to preclude such attacks, I'll be sure to let others moderate my nodes as applicable.
