Is the amount of active users on Lernu increasing and at what rate? Does anyone know?

If you give me a definition of "active" I will gladly cook up some statistics.

Active
1. Visits at least once a week
2. Comment/creates forums posts at least once a week

The following is a list of tuples whose first element is the ISO-week of 2014 and the second element is the number of distinct posters on lernu.

[(1, 135), (2, 106), (3, 108), (4, 91), (5, 119), (6, 113), (7, 94), (8, 100), (9, 93), (10, 80), (11, 85), (12, 89), (13, 88), (14, 84), (15, 79), (16, 102), (17, 102), (18, 97), (19, 112), (20, 101), (21, 103), (22, 109), (23, 111), (24, 102), (25, 111), (26, 98), (27, 111), (28, 140), (29, 101), (30, 102), (31, 98), (32, 122), (33, 102), (34, 107), (35, 121), (36, 122), (37, 120), (38, 115), (39, 113), (40, 94), (41, 105), (42, 112), (43, 137), (44, 100), (45, 106), (46, 109), (47, 113), (48, 117), (49, 99), (50, 111), (51, 118), (52, 93)]

E.g. in ISO-week 32 there were 122 distinct users who have posted on lernu.
YMMV: If a user has deleted his profile, he won't show up in this list.

Only counting Esperanto forums (i.e. 1, 2, 16, 17, 18, 19, 3, 6):

[(1, 84), (2, 78), (3, 75), (4, 61), (5, 79), (6, 69), (7, 66), (8, 63), (9, 54), (10, 52), (11, 58), (12, 72), (13, 71), (14, 54), (15, 50), (16, 64), (17, 65), (18, 55), (19, 78), (20, 65), (21, 64), (22, 81), (23, 75), (24, 64), (25, 73), (26, 69), (27, 71), (28, 84), (29, 65), (30, 71), (31, 69), (32, 85), (33, 62), (34, 64), (35, 68), (36, 83), (37, 72), (38, 71), (39, 75), (40, 65), (41, 63), (42, 69), (43, 76), (44, 63), (45, 72), (46, 66), (47, 57), (48, 68), (49, 57), (50, 60), (51, 76), (52, 66)]

The winners are:
sudanglo, Lakiro, Standardo, dobri and manlajo in no specific order.

There is one user who has posted something IN ESPERANTO each week during 2014!

And the winner is.... Lakiro!

E.g. amigueo has posted in 15 weeks during 2014.

@nornen - Cool. Thanks for all the states. What programming language are you using to do the calculations? Is there a quick tutorial online where I can learn to do that?

Also, can you find the today number of unique posters for each year from 2010-2015.

Wow, 49th place. I thought I was more active than that. But I guess, if I remember right, it was a ways into 2014 when I made my first post. Maybe I'll "rank" higher in 2015 .

Haha, I made it on a list!
