I completely scrapped my other blog and did a fresh install of wordpress with a new deal and everything. Are opinion blogs (easy to write) generally accepted and read by the community?
All depends on what you are writing about? Are you just going to voice opinions on random subjects or do you have a niche you are looking to discuss?
Whats the niche? Politics, SEO, Hosting, Webmaster, Entertainment? I am sure with some promotion, proper keywords, link building, How well connected you are to the blog info - in due time many will read.
It really depends on your ability to write engaging and creative posts. If you are really good at writing and have a way with words you could probably write about almost anything. It would be helpful if your opinion blog related to problems and annoyances people face every day.
It will depend on how you organise it. If you're skilled or writing about topical things then you're likely to get traffic.
