Yeah, I wrote an article two days ago about 2 hours I lost in vain due to the issues on Steemit.com. - It was my own fault though, as I forgot to backup my content before I tried to publish my article... - So I lost it.
I also stumbled upon this error:

When I was trying to reply to & upvote a comment. Never seen that before. A very common issue is the "login" & loading time problem.
As soon as I'm trying to transfer funds or if I'm going back to Steemit's main page to look for other articles I either have to wait for like 20 seconds before I'm logged in again, automatically.. or I have to login manually again as it seems like I'm being "kicked out" for some reason.
That being said, I will never forget to make a backup (copy & paste) my content before I publish something again... But I would love to see a proper solution to these issues we're facing.
Ugh. The tough lessons.
Yeah, I always write and save my content in a separate word processor and then paste into Steemit...
It was awful, but as I like to be positive... - It was a good learning experience. :)
I just realized there's another issue.
I'm a level 66 on Steemit, and I know it said "Reputation Score 66" a couple of days ago, and it still says "66" on Steemd.com
However, it says 65 on my Steemit profile nowadays..
