The little Blog Cymru icon over to the right will take you to a blog aggregator set up by Aran Jones to collect English language blogs about Wales - he also set up blogiadur.com, which aggregates Welsh-language blogs.
If you want to add your own blog to blogcymru, you'll find instructions how there, as well as code for the little icon.
You'll also find a whole bunch of blogs, all of which are more diverting and miles more technically proficient than this.
So I'm not sure why I'm directing you there in the first place. In fact don't go there, move along, nothing to see.
