First hits on online calculator

My online calculators have gotten a handful of hits, and not all by my friends. Things are going slow, and it'll take me a few lifetimes before I get the cheque from Google, but it's nice to get that validation in the Apache log - that somebody out there saw my page in a search result and thought maybe that was what they were looking for.

A whole THREE hits, all of them on the electrical calculators:

• "cable current capacity calculator" - somewhere in Dikgatlong Municipality
• "volt drop calculator cable size" - Cybersmart netblock
• "derating factor for temperature" - University of Venda

Half surprising that all three are from South Africa - but maybe that's just one of the ways Google orders their search results?
