the issue, as i see it is not how many blogs there are but rather how much focus goes into each of them. it is possible to maintain a number of blogs, although switching back nd forth prevents u from spending enough time to develop them. my preference is to develop one successful blog first and then add more once that process is handled successfuly.There are so many ups and downs with each blog that owning and managing multiple blogs is now next to impossible. Lesser the blogs owned by a blogger at a time, higher are the chances for success. Do you agree to this ?
