Hi, I have ~2-3 WPMU installations running on some free webhosts (000webhost f.ex) and have created a simple tool for one-click creation of new blogs on theese WPMU installations. (and have 60ish running as we speak) I have also created a system that syndicates hundres of feeds from sources around the world, and simply creates a new post within a keyword containing the introtext for the indexed article, and a link back to the original source. But i am looking for some ideas on how to increase the traffic. Should i: -interlink all blogs -comment more on other blogs -use twitter more active I use a bit of all above now. etc any good ideas/suggestions out there?
