TypePad and type lists

TypePad allows the user to create Typelists and I've been puzzling over the advisability and usefulness of developing some for this blog.
There are some fairly compelling reasons not to, not least as in the TypePad manual the principle raison d'être of such things is to show the world what you consume, which strikes me as sitting firmly at the solipsistic and trivial end of blogging.
There are four types of Typelist, books, music, people and websites. Of these, the only one who's usefulness is beyond dispute is the last. The first could be quite useful, though at the moment it only works with Amazon; if it could be made to work with library catalogues (through Z39.50 perhaps), it would be much more useful, for example if I could send readers off to a Library of Congress or British Library record.
Music lists again also work with Amazon and nothing else.
Lists of people strike me, but maybe this is because I'm a middle-aged Englishman, as the worst thing of all. I should think that any friends of mine who suddenly found themselves listed as such on a blog would take prompt steps to end the friendship.
