You know who I am?
If you cannot identify me, use the following pictures:
I am not in an order.
You might not know who I am until you visited this puzzle.
I edited my answer and I think you're a
Stack Exchange Friend!
The answers already given for the second and third pictures give us
The first picture is
The end of a bridge or dock or something
The last picture is
Fried chicken legs
So we put them together to get
Stack Exchange Friend
This answer also explains the hint:
"You might not know who I am until you visited this puzzle" because we might not know you (a stack exchange friend) until we saw your puzzle!
Reverse Google-image-searching each picture, from top left, clockwise gives you
1. Bahia Key Rail Bridge (from the Florida Keys)
2. Consumer economics
3. Chicken leg fry kerala style
4. Full stack
From this, plus the hint, we definitely see that part of the answer will be
Stack Exchange (pictures 4 then 2)
This is supported by the
edit history, where (instead of the current "exchange" picture) there used to be a picture of a water glass overflowing, so OP switched from Stack Overflow to Stack Exchange.
I suppose, also, that a liberal interpretation of the first picture could yield
Puzzling, since a bridge that ends abruptly is indeed puzzling, though of course there are many many other words that picture could represent.
And in the category of rampant and ridiculous speculation,
The bottom-right picture could be Meta if you look at it as "mixed meat".
If images use this scheme:
I can read (with a bit of imagination):
1 = bridge
2 = cash => cache
3 = a cake with raspberry? A Raspberry Pie or... Raspberry PI
4 = a plate with something... it doesn't matter. It is a plate.
since these are all electronic references, the mysterious object is an electronic thing with a small computer (CPU + cache), a plate for building my project and bridges (connections) for I/O (input and output). So it is a GPIO integrated circuit.
Yes, maybe I answered with too much imagination!
Cash is in his name, he has done a song called "bridge over troubled waters" and "chicken in black" He also is likes raspberry cake very much as in this photo: http://i.imgur.com/b1rdTBcl.jpg
Its a long shot, but worth it :)
Stack Exchange Spicy Kerala Chicken (Bahia Honda Rail Bridge) of course
It's definitely you! Because, you should be a human being!
So, again, it's you:
Actually I did not know you before I visited this puzzle. Regular community members know you. That's why you used might!
The top left image, while being the
Bahai Honda Rail Bridge, is in the Florida Keys. I think that this might be referencing the word Key
The bottom left and top right images
Are Stack and Exchange respectively
Whereas the bottom right image
Looks like a very spicy, or hot meal.
Making the final phrase potentially
Key to Stack Exchange Heat, referring to Hot Network Questions.
After all, this question was
In the Hot Network questions for a while, so perhaps the OP knew what he was talking about :), Fun images, high views, many answers.
