+ Burried/blind via poll
+
+ Results
+
+I received 10 full answers to the poll - thanks everyone who
+answered. This is a small sample, but this is the best I could get
+(I can't reach more pcb users).
+
+Raw results are available in html, tsv and
+csv format.
+
+
My interpretation
+
+(User obviously means "those users who answered the poll")
+
+
+ - 1. only half of the users would consider even trying pcb-rnd for blind/burried vias
+
- 2. there was only one user who'd consider switching to pcb-rnd for blind-burried vias - this feature doesn't seem to be valuable enough to attract users (details below)
+
- 3. about half of the users need blind/burried via; when they do, they don't use pcb
+
- 4. 9 out of 10 users runs PCB on Linux
+
+
+ My conclusions
+Because of 1. and 2., pcb-rnd doesn't seem to need blind/burried vias. The
+purpose of question 7 was to find out whether users value this feature high
+enough to actually consider investing time/effort in return, compared to
+question 6. This pair of questions was designed to avoid noise that comes
+from the fact that we, on the list tend to express our opinions in vast
+crowds while only a few invest more time than talking and do actual work.
+According to the result of line 7, my conclusion is that it's absolutely
+not blind/burried vias that potential pcb-rnd users need. Thus
+my decision is that I won't spend time on this feature in the near future.
+
+The situation for pcb might be different, tho. I worded the first 4 questions
+to find out how strong the need is among the users of mainline pcb and whether
+they are devoted to pcb or choose the tool according to the design requirements.
+There seems to be a correlation between having to use blind/burried vias
+and using other layout tools. Or in other words: those who are happy with pcb
+usually don't need or want blind/burried vias anyway and those who do have
+already switched to another tool.
+
+This suggests mainline pcb could benefit from burried/blind vias. However,
+the demand is much lower than "every new design needs this" or "no new
+user would consider pcb because of this missing feature".
+
+Linux: it seems pcb power users mostly use Linux. I am not sure if it's
+because PCB works well on Linux and is a bit harder to compile on
+anything else - or the other way around (Linux users are more attracted
+to PCB).
