I update both my facebook and blog accounts regularly.
Apart from that, I have experience in writing articles and reports in my previous employment.
A part of my portfolio includes engaging with youth and university students, so my posts and the language used need to be concise yet simple, appealing to a wider audience, and not necessarily academic driven.
I would be able to write in whichever way you need, either lengthy texts with bombastic words, or short and sweet postings.
