New friends will always wonder who will see them write. Since I write most every day, I will also make a habit of reading their work. So the answer is me. I will see them write.
I'll create a new tab with all their work and not much more. This is so that I get mostly their recent changes. wiki 
I offer the following advice to new writers.
Writing
I've found that I like writing every day. Some days I create new. Other days I groom. Some days I only note things I find elsewhere.
Refer to pages about other sites as if they exist. Make them if they don't. Mention the other site on that page. If it is worth mentioning, it is worth making a place to write about it. See my version of Streak Trick.
Reading
Take notes as you read in your personal wiki. Make this public. Write notes in Incremental Paragraphs. Your future self will thank you for the extra care.
I reserve an hour or so a day for reading. Most of my tips come from people I've followed on twitter. This took some grooming to get a good feed. I look forward to the day this same info comes via wiki.
Make a link like I have above that suits your reading.
Aside: A consultant I met once told me he segregated the pages of his notebooks, left hand pages for what the client said, right hand pages for what he thought.
Read other's updates. Skim down to the journal. If still interested, click the last action to pull that rev up in a separate page. Use that to browse changes. Journal could be smarter about scrolling to changes.
Quoting
Fork remote pages into your wiki. Then write about those pages in your own writing, as if everybody knew them by name. Soon enough they will.
Copy and paste paragraphs from other documents as one big blob. Split and edit these into wiki paragraphs later when you get to reflecting on what you've read.
Drag images to the desktop. Then to a factory. Factory could be smarter.
