Well, it is a good thing you have finally decided to contact those agent. And of a truth these agent MIGHT use your online presence as a gauge whether to accept you or not.
Here's what to do.
You first need to open a blog. For newbie and not-too-techy blogger, I always advise them to start their first blog on a free blog platform like Blogger or Wordpress.org (if you’re not that techy you should start a blog on a free platform first).
However, if you prefer to open a self-hosted blog, it’s all good. The bottom line is you can make it and garner a huge following online with whichever type of blogging platform you decide to use.
The most important thing isn’t your blog, it’s how you present the information to a “PARTICULAR PROBLEM”. So in essence blogging connotes solving a certain people’s SPECIFIC PROBLEM with a passion. If you don’t have any PARTICULAR PROBLEM to solve,
I can assure you that you won’t succeed.
Get one, and make yourself an expert in that “one topic”. That’s the fastest way to grow a following online.
But let truth be told: Every problem you want to tackle now has already been solved. Google gets more than 1 billion searches within 4hrs, and majority of these searches are people – or bloggers – who are looking for problems to solve online.
You mentioned something above: “I'd discuss my revision process, queries, inevitable rejections, and maybe a few non-writing/publishing things that capture my fancy” – these topics are too broad and not clear.
Bloggers have rehashed those topics long enough already, but that doesn’t mean you should give up on it.
What it means is this: YOU NEED TO IDENTIFY YOUR BLOG’S PURPLE COW.
Your content won't get noticed by Google or by your readers if it just rehashes everything else on the Internet. To stand out, you need to do something unique.
Do a thorough research on the top blogs that blog in your topic, and try to find the "thing" that each brand is known for, the unique element that makes them shine.
Your goal is to come alongside the competition and still offer something different. So look for something that none of them cover. This is the gap that you can fill to make your own brand unique. That’s your purple cow.
Without that “thing” in place you and your blog will be lost in the crowd. Something has to make you different in your niche. When people can link your content to some other blogs they have read before, it simply means you are following the crowd. But when you discover your purple cow, people will naturally listen and follow your every word – simply because they haven’t seen anybody present answers to their problem in that manner before.
Remember: Look for a specific people with SPECIFIC PROBLEMS that needs solving, build a blog around those SPECIFIC PEOPLE, research their SPECIFIC PROBLEMS and read answers that bloggers have written on those specific problems. After reading, sit down, craft out a solution to the problem, but this time, answer the specific problem in a UNIQUE WAY. People can’t ignore uniqueness when they see one.
Hope that helps.
