There is one spelling error, and I've removed the ampersands ("&") in the interest of consistent syntax. The ampersands are unnecessary, as the rest of the About page is written using complete sentences, or at least unabbreviated sentence fragments. I've attached a patch with the corrections, including substituting "and" for "&". Reproducible: Always Steps to Reproduce: 1. 2. 3.

learnt is correct spelling: http://dictionary.reference.com/search?q=learnt usage of & is also ok ... it is used to join small ideas/items rather than large sentences (which is when 'and' is used)
Very well, then. I wasn't sure how formal the language was supposed to be; I just went for consistency. And "learnt" sounded a little too informal/antiquated/Texan.
drobbins lives in New Mexico ... does that count ? :) we try to keep the language semi-informal ... keeps the reader engaged with useful info while avoiding dry spells
