The IndieWeb plugin does have quite a few related plugins which all interact well, but you don't necessarily need them all. You can obviously pick and choose based on the specific functionality you'd like to have. Their modularity helps to make understanding what sets of functionality each piece provides a lot easier.

In particular the two that will recreate most of the requested functionality of wp-social above are [Webmention ](https://wordpress.org/plugins/webmention/)and [Semantic Linkbacks](https://wordpress.org/plugins/semantic-linkbacks/). These provide an endpoint that Bridgy can target to send your comments and likes from other social media sites. To my knowledge, they don't require any settings or set up other than uploading and activation.

The other sub-plugins within the larger IndieWeb suite add supplementary functionality if you want/need it. This also helps to cut down on code bloat which can slow your site down. In fact, if you only want a few in the suite, you can install them separately from the larger plugin. The others also help to not only extend functionality, but to better automate portions of it.

They are all also are being actively developed/supported on GitHub.
