This link had some good arguments against exposing auto-incrementing numbers on a web page.

But generally, web developers feel uncomfortable exposing IDs that allow guessing other IDs by just incrementing or decrementing a number. Many resort to random, multi-digit IDs instead.
On a more obscure note, numeric IDs may also allow competitors to estimate your growth by keeping track of how the incremental value increases.
When working with an HTML page, the attributes that you need depend on the plugins that you’re using.
Name Attribute:
Used when submitting a post.
ID Attribute:
Used by Jquery to find an element when doing a $(#id_name).
Used by CSS. Prefixed by (#)
Class Attribute:
Used by CSS. Prefixed by (.)
I didn’t cover all of the cases, since I jotted down what I remembered, but it is a good idea to create a table for this stuff.
