Wordpress is lot more striking features and it gives us control to convert our imagination in to a full fledged website. It doesn't cost us a dime and yet provides us with rich features to flaunt with. It is tightly integrated with the social networking sites such as twitter, facebook, linkedin etc, which makes the user interactive with the website. It has lot many themes to choose from as compared to other free blogging websites. The statistics of the websites is also something which is appreciable enough.
The free version doesn't allow embedding Java Scripts and other applets which kinds of restricts its scalability. Lot's of spam comments are observed in wordpress blogs, though it distinguishes the spammer's but yet we need to read between each comments to identify the genuine comments from the spammed ones, which is quite pain staking.
Wordpress is what you need to opt for if you don't want to do much of fancy things around. Keep things simple, yet make use of the rich intuitive features that can help build a nice website.
Wanted to start a blog on a technology i was conversant with, but didn't want to spend too much on the webspace and web designing part. Wanted to share the experience and knowledge with users in the same domain. I wanted the freedom of putting my imaginations on online, yet not bother too much on the efforts that would be required. Wordpress very much served the purpose. You can visit fullonbaan.com to see how it eventually shaped up.
