Are blogs really usefull !!!!!!!!

Yes blogs are really useful. Many people earn thru their blogs. Some people have good writing ability and for those blog is a good source of income. Some persons use it to post their referral links. As for as my personal preferece is concerned, I will choose making a website than writing a blog. In website you have more freedom than in writing a blog for some other website. You can do anything on your own website. But this is not possible on the bloggers site.

Yes, they are indeed. Just find the right one especially that relates to your interests or something you're searching for. Many blogs are now useful and resourceful to people. Though i do admit some people just get excited on creating the blog but just too lazy to update them.
