I should clarify: with Yahoo plus you only create one base for all your sub-addresses, not a new base for every sub-address. So in my earlier example, if you wanted to sub-address ebay, amazon and hackernews you'd have huggybear-ebay@, huggybear-amazon@ and huggybear-hn@. The big deal is that huggybear@ != someone@ and sending to huggybear@ won't reach someone@ and likely earns you a place on their blacklist (or some points towards ending up there).
