Will my creating and hosting a popular online educational website improve my odds of admission to grad school?
First, I am neither Canadian nor a pharmacist, so take my advice for what it's worth.
From what I can tell, you website / seminar series is already well developed, has been used by many students, and is quite popular. I will not speculate what weight this will carry toward graduate admissions. But whatever this weight is, I suspect it will not change much if you put additional time/effort into further development. You already get credit for &quot;having built an impressive educational website&quot;, so there is not much room for improvement in this area.
On the other hand, I would hesitate to say that any further work would be &quot;a waste of money and time.&quot; It sounds like you are providing a great service to the community, learning a lot, and perhaps even having fun. It is unusual for &quot;outreach&quot; initiatives to be this successful, so I would not discourage you from continuing if you were inclined to do so.
