I'm really pleased with my mum. Less thank three years ago she had never touched a computer in her life: now she's using eBay, she's registered for and using a Gmail account, she reads the Sydney Morning Herald (online from our house in Kuala Lumpur in Malaysia!).
Now she's using a Del.ico.us account. It's not a blog per se, but when she finds something interesting she posts it, sometimes with descriptions. If you're into jewellery, gemstones, weird news stories and necklaces in the shape of the Enterprise A refit from Captain Kirk's era, check it out!
