As a presenter, I absolutely HATE doing online presentations! There is no opportunity for audience feedback or questions. Similar to lectures or speeches, it's just me doing all the talking without knowing how well I'm reaching my audience. I much prefer the interactivity that an in-person session provides. No matter how many times I give a particular presentation, each live session is different because of the audience. Smaller sessions also tend to be more dynamic because people feel more comfortable interjecting questions and providing answers.
I really love the way that I can involve attendees in my session. It reminds me of when I taught college classes because I encouraged the class to be a place of learning, asking questions, and looking at things differently. You really can't do that so easily in webinars or recorded presentations.
That's not to say that webinars don't have their uses. When I'm looking for a specific answer I can pull up a recorded webinar, fast forward, reverse, pause, etc. Mainly that's needed because I can't ask questions, but it can be a time saver. Short, focused videos can be really useful and that's why they're so popular on YouTube.
But, when it really comes down to it, I like to see my friends in person. While I enjoy sessions by Grant, Steve, Brent, Kendra, etc., I really enjoy sessions by new speakers who are finding their comfort range and personally growing in giving presentations. In those cases, the subject itself is often secondary. I had a lot of mentors when I first started speaking, and I love being able to pay it forward by mentoring others. It's wonderful to see a new speaker's comfort level increase because they have seasoned presenters in their audience to support them.
