More often than not, bloggers hit a mental brick wall which would hinder their creativity when producing new posts. Every blogger has experienced this at least once for many different personal and environmental reasons that forces them to stop blogging for a few days or even weeks.

There has been a common misunderstanding that linking some how affects your ranking negatively, as though you bleed page rank or something. This is of course wrong and many websites have been penalised when not enough out bound links have been established.
