Blogged Down (3)

What prompts a reader to seek a blog? I can think of four categories, none cut-and-dried, nor exhaustive, nor bullet-proof.

(1) To be entertained*
(2) To learn something about the world, if it is only to re-assure your own view**
(3) To listen to a blogger, particularly a friend or personality***
(4) To be usefully informed--this appeals to self-interest****

*A library blog that entertains is an oxymoron.
**The library blog may touch upon the world-beyond-the-library on occasion, but not enough to attract that kind of reader.
***Since library blogs are typically corporate or impersonal, the hook of a friend or personality is missing.
****So a library blog must exploit its niche as being relevant to students and other library users.
