I agree, not a day goes by that there isn't an item closing.
Plus since I have an eBay store, I can put it on vacation for an hour or so and bring it back online. (with a message that Southern Jewel's Fab Finds is away from her computer and will be back <fill in the blank> to answer your questions.
Also, I run one sale a day via my store. Normally five percent on a single category.
These all help to reindex my auctions on a daily basis.
