personally i'd get your own website and not use a blog website, people dont tend to take those as seriously.
You can host a site from home and buy a domain for as little as a pound a month, so its fairly inexpensive - just need to create it. But then, theres hundreds of templates you can modify for free.
You can write much better than me, but if i were you i'd gear your articles towards something people want to read but from the articles i read they seem pretty random and unrelated to one another
but then thats where its good to have a site, with different core areas with something to offer readers.
overall, pretty good
