I agree with all of your points.

I've found all the great posts and accounts as a result of Google searches, including this one.

How will people stick to Steemit, if they can't find any decent content via trending and hot tabs? I don't even mention the new and promoted tabs.

What I observed in my first three days is that people don't act here naturally as they would in other social networks, such as Facebook. They avoid upvoting to avoid losing their voting power.

The fact that you can't resteem an older post doesn't make sense either. This is internet. You should be able to resteem something however old it is.

One more thing. Be careful whose post you flag. If they turn out to be a whale, they can kill your account.
