Compulsory There In The Widget Blog

Actually, if the widget is? I think part of the widget is a blog that has a specific function. This widget is usually placed on the sidebar, or at some theme provided a place in the footer, header etc.. Then the widget is a must have in a blog?
you need to remember this is all just based on my observations of it:

1. Recent Comments. function of this widget is displaying the latest comments either from visitors or from your (admin) itself. Well other uses of this widget is the presence of the new visitors, will know about the article where the last comment. and usually, the article commented = article interesting or otherwise :-).

2. Popular Posts. function of this widget is to display the most popular articles, can be based on the number of comments or pageviews. and almost the same as recent comments, visitors will think "What exactly is the content of this article can be a really popular article".

3. Random Posts. function of this widget to display a random article, this widget is very useful when visitors are confused about doing the blog, now with this widget is not expected visitors quickly left the blog.

4. Subscribe. Actually this is only optional, but since I also use it so I included here.function for visitors to subscribe more easily when the article of this blog. several themes such as V2 trick. already providing this box to subscribe. so no need to use the widget.

While some widgets such as Recent Posts, Statistics, Category etc. It is not necessary, but for Recent post that may be required as well, and the category becomes mandatory if you do not use wpcustom dropdown menu to create a category.
