Oh yes, the tag filter will be useful.
One suggestion for the post editor: allow for usage of a custom signature, so users don't have to keep copy and pasting their "signature" at the bottom. It'll be even better if I can create a custom signature that offers users "My Recent Posts in this Area" and then generate the latest 3 links with that tag on my blog. Now that will really be useful and make me want to use OnePlace.
Thanks for your comment and ideas! We do plan to add recent/relevant posts in the bottom of posts in our design.
You're welcome! All the best with developing the platform! Hope to hear more about it soon =)
