I have to admit - it's great to make a quick blog entry using my Wi-Fi Palm. You can be anywhere around the house (relaxing watching TV on the couch or outside on the sundeck) and quickly make a blog entry via email.
If you want to have a blog that is mobile screen size friendly, then have a look at:
www.tumblr.com
Once you create your blog it can be viewed as a regular web site or as a special mobile site. Tumblr automatically reformats your blog to mobile size.
