hey salt - i know what you mean. Ive been boosting my cv with as many publications, conference papers, awards, scholarships, research and lecturing opportunities as possible. Like you, I had a 2:1 undergrad degree (which I was rather pleased with though) but as a postgrad with 30 other postgrads you really need to stand out from the crowd and define yourself from others. Those distinctions help too - shows how well you can do in contrast with others!
Were you employed as a lecturer, or were you like an assistant lecturer? ive been a research assistant for a couple of years and have been asked to give the odd lecture here and there to cover for absent staff etc.
