It is worth spending time writing in good English and be conscious of your spelling and grammar. I am not saying that I am good. I am still learning every day and on every post to write better English.
It is also worth paying to get your own domain. I got an offer through BDMM community to write a post for an advertiser because I have my own domain and I write well. I was surprised because all this while I have no confident in my Malaysian English. I really praise God for that. :)
