Disqus vs. Reblogs
Some people simply rely on reblogs as a way to comment to other people’s posts in Tumblr. It works like:
A friend/person posts an interesting post, another person likes to say something about it so he reblogs it with his own commentaries.
One problem that often arises is when it circles around. So basically the original poster re-reblogs his posts for the nth time. It’s like they’re using Tumblr like a forum.
Sometimes, while reading through their posts, you couldn’t tell who actually started the thread/conversation.
That’s the problem with Reblogs. Tumblr is not a forum, where you see thread of conversations across different blogs.
The problem with Tumblr is it does not have a built-in commenting system (although I read somewhere that it’s in the works). A problem that long has already have a work around.
Installing or integrating Disqus into your Tumblr blog enables you to have a commenting system at your blog. Why not use that feature so you can keep a thread in one place. Installing is not that complex at all. If you know how to read and follow instructions, I can’t see a reason why one cannot install it. All you need is a Tumblr blog and sign-up for a Disqus account.
