If you currently are paying for a listing with Look Smart this article is important to you.  From everything I've read this effects those of you that currently have a listing with them.

For sites that get 100 clicks per month or less from LookSmart and its partners, first-year costs be a minimum of $229.00. Subsequent years would cost a minimum of $180.00. These numbers come from the $49.00 setup fee for new URLs, plus the minimum $15.00/month clickthrough charge per URL. Clicks are 15 cents a piece, thus the 100-clicks-per-month number.  If your site recieves more than 100 clicks per month the fee could easily reach thousands of dollars.

You're also only allowed one URL per domain under the Small Business Listing plan, and subdomains are considered part of the same domain, according to their FAQ. You can pay them extra to have keywords associated with your listing. It's difficult to say whether your site will rank highly enough to get any clicks if you don't associate keywords with it. You can pay for additional categories, description changes.

This new fee applies to existing customers that have already paid their fees.
