I pointed out on on 4th Aug 2009 that Wordpress 2.8.3 is available. Barely a few days later, my dashboard in my wordpress admin says “WordPress 2.8.4 is available! Please update now.”. Can you really keep up with the changes in technology? Too many chefs can spoil the soup, they say. I hope with all the hundreds of themes and plugins being contributed to give wordpress users a great blogging experience, they do not take away the joy of building websites.
This feature is available only to wordpress users who have their own domain name (self-hosted wordpress users) at wordpress.org. Wordpress.com, however, is a free hosting platform. You need not have to concern yourself with the changes. For new bloggers, who intend to use wordpress as the site building platform, it may be a better idea to create a psuedo blog on wordpress.com because two things:
1. Community support:
instantly you have a group of people your can invite to view your posts without going out to promote at other social sites.
2. Server support: not worrying about breakdowns, bad service from domain providers etc. I have been there. My main site had crashed twice and I had lost all my data once. Had to pick myself all over again. So lesson is, unless you are ready to take a fall, try out the blogging platform available.
If you run your own website, you are practically working on it alone. lf there’s a bug or you installed a plugin that ends up spoiling your dashboard, you have to seek help at the wordpress forum and sometimes, you won’t even know how to begin describing what the problem is! There is a lot of jargons you have to learn. Wordpress.com provides exactly the same dashboard or admin features as those on self-hosted wordpress sites. You may wish to migrate to write on a self-hosted platform in future.
