Using descriptive labels is a very important usability issue. If you don’t use the correct words in your website, users will don’t see all those great services you offer.
An example is MizPee, a weird website that helps you find clean toilets. Aside from buttons like “Add Toilet” and “Find Toilet” they have one called “Looisms”. Is it me the only one not understanding this?

They have also placed a button called “MizPee Me!” instead of something like “Send me an SMS” or “Send me the application link”. I don’t really know what that button is for.

I don’t really know how useful this service is, but this people need to improve the interface a little bit in order to make it clear what the website is about and how it works.
