The arrival of twitter lists has led to a frenzy of list publishing along with widgets and gadgets and even a dedicated on line directory called Listorious. My issue with the majority of these lists are that they are too long.
As a contribution to the current list mania I am publishing a top 20 PR and social media list of lists. The criteria used are that in addition to being on subject, all of these lists are of a manageable size, specifically they list between 10 and 50 accounts. The figures quoted after each list are the number of twitter accounts that they include at the time of publication.
