Do your visitors know your site at first sight ?
While making a great content site, one thing which is very much important is that your keep it as much clean as possible. There is know use of fancying your site for nothing. Keeping all widgets and plugins under this planet so that your blog/site looks great is actually nothing but a foolishness. Firstly, if you have made your blog for only SEO purpose, then of course its no use designing your site. And if for quality purpose, than people will look at some worth reading article on the site. Designing, themes, widgets, etc. are just for a bit flexibility to visitors. There is actually no use of confusing your visitors with tons of widgets and extras. Maybe, if you are new to blogging, you may do all this fancy stuff but at later stage you will realize that this is pointless.
