Maybe this is getting ahead of myself, but another way to add value to the site (for learners) has occurred to me...
The site could be a way to find & connect with teachers not necessarily affiliated with us.
I just met with a potential student who isn't able to travel to our location to study. She lives in Seoul and commutes to Asan via KTX, and therefore requires me to meet her somewhere around the station for lessons. @mine-lee and I started debating the pros & cons of this arrangement -- then it occurred to us: why is this Seoul resident looking for lessons in Cheonan? There is no shortage of teachers in the big city. In fact, last time I checked, the supply-demand dynamics amount to lower prices up there!
In a similar situation, recently a student of mine from a company gig, a late-middle-aged gentleman who stays in Asan all week but lives in Seoul, asked me to help his daughter with flight attendant interview prep, and she did indeed schlep all the way down here (she got the job, too - cough, cough). But the same question is begged - why are these people not connecting with any of the swarms of capable teachers up there, more conveniently located & willing to work at a lower price?!
What if the answer is that a lot of people want help but don't really know how or where to find (native) tutors. Maybe they are not interested in schools or agencies (the formality, the overhead, perhaps a past experience left a bad taste, etc, etc). Or, maybe schools/agencies are a viable option but it's just too much work to find a good one.
So, this site is imagined as a community; a social network, a miniature facebook for *our* students and teachers. What harm would there be, tho, in opening the same platform to other teachers and other students?
Going back to the lady I met today - one of the solutions we came up with was to politely decline the arrangement but promise to find another private tutor to meet her at the KTX. That wouldn't be too hard for us, since we know quite a few teachers down here. I still feel like telling her, tho, that she should get a teacher up in Seoul. I could point her to craigslist, maybe, or ask around the various foreigner facebook groups.
It's still a big shot in the dark for everyone involved, tho, and that's a problem I'm thinking this site might be able to help solve. Teachers & students alike have profiles (dedicated to their role as teacher or learner), points & badges, maybe a trail of content. There's mail, chatting; there could be clearly defined places to "ask around," such as 'Teachers in Seoul' or 'Teachers in Cheonan.'
Next question: How is this not what facebook already is?
As touched on above, the whole platform is a space dedicated to English learning. My identity here is compartmentalized from facebook where I network professionally but also argue about politics, chat with long lost friends, plan soccer games, etc. It's not full of ads or links to apps & games or cat pictures or news about Donald Trump. The teacher is here to network professionally, not to buy & sell furniture, complain about ajummas who cut in line, or ask where the English-speaking dentist is. The student is here to work on their English and/or find a tutor.
Well, it's an idea. It's not really anything I'm not already planning on building, except for building it with the notion that teachers & students other than us & ours would want to use it.
