A blog is an online personal diary.. A personal diary should be filled with information what we have gathered in our own writing… Do you need to use your diary for filling others thoughts and feelings?
Great bloggers are the ones who express what they are master in it , say a finance expert writing his views on economy, his interpretations.. If you cant express things in your own words, a blog is not for you !!
Do you need a blog to copy paste what others have written or uttered ??
This approach is absolutely wrong, unless you express the same in our own way/easily understandable manner, with some extra information/interpretation, copying articles on internet and publishing in ones own blog is stupidity at first point next to legal issues, search engine copy content penalities etc..
