YouTube playlists of HaD entries.  Videos culled from entries with video link - some are not "contest entry" but just progress update, etc.  Split into four playlists because YouTube limits to 200 videos / playlist.

As noted by davedarko: "wow, so if every 445 put up a 2min video, this means 15hours of video material!"

14hrs, 50mins to be exact.

RoGeorge provided this insight:

"At the moment when the input data was sampled,
- there were 718 hackers with a total of 791 projects

- 1 hacker with 6 projects ( http://hackaday.io/hacker/636 )
- 3 hackers with 4 projects each
- 10 hackers with 3 projects each
- 39 hackers with 2 projects each
- 665 hackers with 1 project each"

This chart shows submissions over time.  Orange line indicates projects which met requirements, while blue displays all submitted projects (so, obviously, orange < blue).

The final 7 days accounts for over a quarter of both submissions and valid entries:

Submissions (final week) = 259

Submissions (all other weeks) = 533

Valid Entries (final week) = 120

Valid Entries (all other weeks) = 325

The busiest day was Aug. 20, with 75 submissions (27 valid), although the best day for validated entries was Aug. 19 at 38.  Incidentally this reveals a discrepancy between hackaday.io time and hackaday.com time: 51 further submissions (13 valid) arrived on Aug. 21, the day after the deadline : )

Project Log statistics - this chart shows the number of project logs per project.  Most people posted either 0 or 4.

Average number of logs per project: 4.284 logs

Average, 0 excluded: 5.693 logs

Average, 4+ only: 6.765 logs

Top three bloggers:

* http://hackaday.io/project/1279 (44 log entries),

* http://hackaday.io/project/964 (49 log entries), and

* http://hackaday.io/project/996 (57 log entries!)

Thanks to user rawe, who provided this awesome chart tracking daily image uploads to hackaday.io over the past few months, along with significant dates!

Since there are tags on projects, there can also be tag statistics!  (Excluding "thehackadayprize" here, as it was by far the most common tag).  Tag cloud from the list of valid entries.  You guys with completed projects are way ahead of the game.

Top 20 tags, with number of uses:

120 ARDUINO
47 ROBOT
39 RASPBERRY PI
30 WIRELESS
29 COMPLETED PROJECT
28 ARM
27 BLUETOOTH
21 WIFI
19 LED
19 HOME AUTOMATION
18 IOT
18 AVR
14 ANDROID
12 RADIO
12 MICROCONTROLLER
12 LINUX
12 CNC
11 SERVO
11 OPEN SOURCE
11 INTERNET OF THINGS

1,220 tags were used only once.  Some personal favorites...

"#SoMuchSpace", "Canada Eh?", "Cthulhu", "DidIMentionAwesome?", "Earl Grey Tea", "For the good of all of us" / "Except the ones who are dead", "Gizmo for You", "High Likelihood of Crashing", "Mind Control", "NOT Arduino", "Pee" / "Poo", "Purple Monkey Dishwasher", "SimpsonsDidIt", "Space Jellyfish", "SPAAAAACE", "SPAAAAAAAACE".

True to Hackaday spirit, only one person mentioned SAFETY.
