Point taken. Our pricing is actually really cheap, between $6-11/mo for an account, and it's a lot less for institutions. We were torn about this, because we wanted the front page to be clean and clear (right now it's like a landfill of accumulated patches and additions, but take a look at http://www.skritter.com/frontB for a look at what we'd like to move to). Do you think that on a more simple homepage the pricing information distracts from a conversion goal, or encourages it?
Almost every online service I've seen has a "pricing" tab along the top. The prices don't need to be on the main page, but they should be easily discoverable. It seems suspicious to me when it's not there. My 2c.
