What are the necessary things that should be in the blog.

mate,the most important thing in the blog is the content and how fresh it is. nowdays we all see almost everyone comes up with their blogs but their isnt any originality in the blog.people tend to copy and then get frustrated that they didnt get traffic to their blog but actually its because of the repeated content they post. so if you really want to make an attractive blog then first find some original and fresh content to grab the attention and besides this i think the look of the blog also matters sometimes.means how attractive one makes his blog. the templates,different animations etc etc. i would suggest you to use blogger for blogging. hope this helps. regards. keep mylotting. :D

My 2 cents worth: 1. Original content 2. Regular posts (at least 2 or 3 times a week) 3. Pictures/Photos/Videos will help to make your posts more attractive. 4. Incorporate the social bookmarking widgets like AddThis to improve the efficiency for your visitor to share your blog... Hope it helps. Cheers!

It really depends on what kind of blog it is. I would suggest having lots of content and make sure you post once everyday or every two days. I would also add a stats button so you can keep track of how many people visit your blog and where they are from. I also like to add a chat box when I made my blogs. This allows your readers to leave you messages and chat with other readers.
