It looks like you are posting to various third-party services and then aggregating them into a feed on your site. It looks great and functions well but obviously you are at the mercy of these third-parties should something go wrong (they cease operations, change APIs, etc...).
I very much like the idea of posting everything from a primary source which I control, then pushing it out to the third-party services. Easier said than done of course, but it's something I think there is demand for.
I initially planned to open source it, but then I decided I'd rather just do my own thing without having to worry how it works for others, and especially how they would upgrade it when a new version comes out. But I recommend it wholeheartedly. Make your own CMS and have it do exactly what you need it to do, with all the metadata you could possibly want!
For example, recently I added the ability to add a date to nodes, as exact or rough as I want (millenium, century, decade etc up to specific days... I don't even have a use for that currently haha, I just wanted to have it). I don't just have tags, I have several taxonomies, some just visible to myself, nodes are nested in two ways (imagine every comment here could also have a "subtree" of comments, ad infinitum), and I could even use it to make something forum-like if I wanted to, since each node has settings for who may attach what to them, and who may attach what to those nodes in turn, several levels deep. It was a lot of work, and the code sure is ugly, but so far I have seen nothing out there that even tempts me to switch. Nothing fits me as well as the glove I made for myself :)
http://a.sandboxx.org/johann/ is where all the content lives, at http://johann-lau.de/ you should see a photo slideshow which comes from http://a.sandboxx.org/johann/photos/ and be able to toggle a music player that is fed from http://a.sandboxx.org/johann/music/ (the music is my shame, I can't even master myself out of wet paper bag haha, using free beats by people who know what they are doing is one of my resolutions this year), the music player is also shown at http://aww.johann-lau.de/ if you scroll up, hover over the bird and then the musical note. http://ilikehopefulstreetart.johann-lau.de/ only shows a subset of the photos (all photos that have the the tag "ilikehopefulstreetart" in a hidden taxonomy), and there is also http://favouritequotes.johann-lau.de/ which is very simple (click to display a new quote, they all come from http://a.sandboxx.org/johann/favourite/quotes/ ). I'm yet to combine random quotes with random photos. Oh, There is also http://a.sandboxx.org/johann/meta/ which are mini-mashups if you will, that reference : my code is not very D.R.Y., but the resulting website kinda is ^^
I believe https://hootsuite.com/ is this sort of thing, but I haven't looked into it myself. I don't know how well it integrates into your actual "own site".
edit: also https://onlywire.com/ seems to be the same sort of thing. I've just found these by Googling, though.
Shortening the animation length on non-mouse-wheel page scroll may help.

What I envisioned was a social network, where in order to become a member, one must be the verified registered owner of a domain, where their social media newspaper would be displayed. More detail here: https://news.ycombinator.com/item?id=6529523
I look forward to your mobile optimization, please do a follow up Show HN when you accomplish that. Best of luck.
There's more you can add to this, such as 4sq check-ins, Instapaper/Pocket readings, YouTube watched, etc.
Then I realized that it's just FriendFeed, if you bother to add a social element.
