Hi there,
at present I can publish to facebook and twitter but reddit seems to be MIA
We don’t support Reddit at the moment but if you want you can submit a feature request here.
Our dedicated team will take a look at that and get back to you with questions or feedback if needed.
Jetpack also comes up short on the mobile speed test from Google
probably due to the bloated nature of JetPack
It’s a myth that Jetpack slows down or your site. Most of Jetpack is designed to speed up your site by taking the load off of your server, like our site accelerator, stats, subscriptions, and related posts, which are all processed on our end (rather than hammering your database). You can also make sure that you’re only using the Jetpack modules you want. Here’s how you can control (disable/enable) modules: https://jetpack.com/support/control-jetpack-features-on-one-page
might be safer to carve it into pieces
I’m not sure if you know about this, we recently launched Jetpack Boost and Jetpack Backup as a separate plugin. I would recommend you to try Jetpack Boost in order to make the site score much better and if you have any questions related to Boost, you can ask here. ??
