The blog feature of weebly has an option to connect it to a Facebook account. Which in turns requires an email account. Which in turn allows Facebook to access the address book in said email account, and who knows what else. That's too scary for me.
I noticed that there is the ability to 'Like' posts (and indeed some do have likes - which is immensely gratifying to me as it means you like aspects of this blog) but I have no idea what happens if you do so. I assume these Likes have something to do with Facebook.
I am an old stick in the mud curmudgeon who is deeply suspicious of this whole social media scene and precisely what it is 'they' do with your data.
As it is I am somewhat piqued that my website is trawled and catalogued by various net bots, spiders and crawlers, with images and information appearing on other sites throughout the world. Deeply worrying.
