I don't think any of the other Hive 'frontends' have it, but I'm sure more will add it in future, anything to help the Hive community buzz. I agree; simplicity is key. We're constantly trying to improve the ease-of-use features on slothbuzz, including our 'engage' section.

It's great to see more Hive projects growing and finding their buzz! HivePulse is a great tool for everyone! So many awesome tools on Hive don't get enough attention, so it's great to be able to spread the word!
