I respond to comments on my blog posts quite regularly if I have something to say—you should get an email if I reply to you. If that feature doesn’t work, you can always check back on my blog.
You can email me at email@example.com (this is a disposable email address; if you email me you will receive a reply from my actual email address). I respect meaningful subjects, and am happy to answer any general questions about my blog or anything I’ve written.
I do not currently accept guest posts on my blog. I will consider advertising for a fee, but links and placement are to my discretion, per my terms and conditions. I also don’t mind helping people, but I will not answer coding questions as many of the posts on my blog about coding are outdated, so please post in a community forum instead.
