LOVE AT FIRST SITE

I have been doing a lot of thinking in regards to starting a blog, is it really that effective.. everyone posts about fashion and events and etc.. Will it just be repetitive if I interact with the same stores and same events.. Then I did some more research saw some really cool sites like Vitamin Daily and Christie Lohr's mystyle journal.. these groups of trendy and event hopping ladies have really put out a name for themselves.. so I guess if I have to be repetitive and post things you have seen before so be it!!! HAPPY BLOGGING!!!
