Some closer friends might, but several of these people doesn't have my phone number or email. I participate in several groups and people often write "does someone want to do something today?" etc. To message every single one every time and ask would be too much of a task. Of course you could create a mailinglist but then you'd have to convince everyone to use that instead which I know would be impossible. But to answer your question, yes.
