Thanks! :)
Vector rendering is slow only in IE versions <9, when the VML renderer
is used. SVG and Canvas renderer is working fine for other browsers and,
I guess, also for IE 9.

Hi Janis,
thanks for the feedback. I'd put your points under the following
headlines:
"Slow vector rendering expecially in IE",
"Make standard use-cases super-easy (e.g. popups)",
"Cleanup examples to keep them in sync with the API"
OK?
Best regards,
Marc

A couple of problems I can think of right now.
* The slowness of vector layer in IE without Canvas support (up to
IE8, I guess?).
Zac mentioned performance warnings when adding more than 1000
objects. I get problems with IE7 when adding more than 100 objects.
In my case they are text labels each constructed of two VML elements.
They could theoretically be replaced by DIV elements, but probably
better just wait for people to upgrade their browsers. A workaround
is to measure and control the performance by OL library user script.
* The clumsy (not strightforward) way to get a marker (not
necessarily meaning the Marker class here) on a map that display an
info pop-up upon a mouse click.
I've seen many posts where people are asking help on this,
even though it would seem one of the basic features one would want to
do with a map. In addition, it seems that there are several ways to
do it, some official examples offered are out-dated and actually
supposed to be deprecated (the Markers layers altogether, as I
understand), and some functions supposedly (as per documentation)
creating pop-ups do not work or do not work as it would seem they should.

Hi all,
for my talk "Common pitfalls for users of OpenLayers" [1] at this years
FOSS4G [2] I want to evaluate the parts of OpenLayers where users of the
library experience problems.
You would help me -- and the project itself -- a lot if you could answer
in this thread and tell me what problems you had working with OpenLayers.
Please do not hesitate to tell us what has bugged you, what was unclear
or non-intuitive. Provide us with the sall and the big annoyances Of
course you are heavily encouraged to provide ways around the pitfalls
and possible enhancements.
I want to identify areas which often cause problems... and eventually I
plan on making the library better where this is possible.
Anyone is invited to share his/her thoughts -- so if you want the
library to improve, go on and tell us where we can make things better.
Thanks in advance,
Marc
