If you have problem with hosting service or your wordpress blog has taken lots of time for loading, perhaps you can consider to install WP Cache wordpress plugin to generate static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

My web hosting is quite reliable,so far I don’t think I will need this plugin at this moment. If you need to speed up the loading of your blog and your blog always hit Digg.com’s frontpage, then you are encourage to activate this plugin.
