A blog post requires an account with a blogging provider or a hosting provider though, so I wouldn't call it a lower barrier if you don't have it.

Besides that, the context matters here. This post is riding off of the attention that another Skyrim WTF bug got recently, which was posted on Twitter. Continuing the conversation there seems like the lowest barrier to entry to me, considering that the author already has a Twitter account and a following there, especially if you actually want to reach people that might find it interesting.
