I am not new to building and promoting my websites but I just started blogging a few months ago and joined mybloglog.com. Boy do I feel dumb! First I went around joining all the communities expecting to find message boards but now I have figured out that there are no message boards but that each blog is a community. So, what is the purpose of joining communities? Is it just to get noticed? How do I participate in the communities once I join? Also, are tags supposed to be like keywords? If so then I can see why I would add tags to my own member page but do I also add tags to the other member pages and communities I visit since there is an option for that? If so what is the purpose of doing that? I can see why I would add to my own but not why I would add to others. I feel so dumb when it comes to this and social bookmarking in general. Is it just me that finds this confusing? I have read over everything but but still not getting it. I just feel like I understand the concept of it all perfectly but none of these sites explain things very well. Thanks for the help . My blog: www.blogawaythepounds.com
