I've never been a fan of on-line reading groups although i think sharing recommended book lists is a good idea.For a reading group to be successful, i think, it has to be face-to-face such as in book club circle. Perhaps instead of some members addressing branch meetings in talks after the business part has been completed, sitting down to discuss a particular book or even an article (perhaps from the Standard) could be just as worthwhile in the education process of members. I feel attempts with the large tomes like Capital is not likely to be fruitful but the more "light-weight" pamphlets such as Value Price and Profit or Wage Labour and Capital is more ameniableWorth giving it a stab i think and perhaps become a focus for starting socialist discussion/education groups
