I’ll just go ahead and post the reasons why you should be using wordpress.com instead of the competition when it comes to business blogging:
1. Easy to use - the dashboard panel is the most user friendly out there. You don’t need to know any html or css or anything else to use it.
2. Huge selection of themes available
3. Highly customizable header image
4. Extremely good anti-spam protection - you won’t have to worry about anything related to spammers.
5. Ad-free and scam free - a very reputable platform, no scamming blogs there.
6. Better design
7. You can comment even if you don’t have an account - so that all your clients will be able to leave a couple of words for or about you.
