I mainly use Twitter and Facebook for my social media though really the best way to guarantee being updated is to subscribe to the mailing list.
Facebook is fairly unreliable with the number of posts that are distributed without paying for promotion. One way to improve the liklihood of receiving Facebook posts from me is to hover your mouse on the Like button near the page's name "Andrew Shearer (www.andrewshearer.com)" (or at the top of the page itself on the "Like" button). In the drop-down menu select ADD TO INTEREST LISTS. Then create an interest list (and make a name for your favourite sites). When you select that interest list you will again get all of my posts and not just 10% of them.
I also have accounts with the social media below but Twitter and Facebook are the ones that I use to communicate my news.
