Why? Because you found something funny or incisive. We hope.
We signed on to a Domain name, and a slightly higher level, up from Free to Personal, at WordPress to gain access to an ad-free blog, more storage, a few more display controls and a cool Domain name: Londontlife.ca. No ads and better colours makes for a nicer experience.
We are signed up through Stripe as a non-profit as Londontlife. The blog should cost about $30 this year, and likely more next. On our current plan, WordPress.com charges 8%. Additionally, Stripe charges are typically 2.9%+30c
So, roughly $0.50 of a $2 tip. Check again on the About and Submissions page. We are doing this for free, and because we can.
