I've never taken part in the postcard exchange but I am thinking about signing up for the next round. This is after Steve at the Lighthouse showed me the wonderful cards that he has been receiving. The thing I liked most about them was the diversity, both of materials used & subject matter. It seemed that people just felt free to express themselves however they pleased. I really don't like the idea of a theme as it will probably suit some more than others. E.g. if the theme is self portrait, or even portrait then I think a lot of people who mostly do landscape or still life or whatever would perhaps feel a bit sidelined. Certainly for myself I'd like to think that if I'm taking part that I can choose whatever image I most want to send without any thematic restrictions.
