One thing I miss when trying to do portal work...
... is the incredible amount of knowledge that exists in the form of discussion forums, web sites, and newsgroups (not necessarily in that order).
I know when I run into a Notes/Domino problem, the issue has almost surely happened to someone else, it has almost surely been asked about in a forum, and the answer (or lack thereof) is out there if you keep looking. Having a decade of postings available at your fingertips helps solve SO many problems so quickly. If it weren't for MartinScott's SuperSearch, I'd be lost.
But when doing Websphere Portal work, the accumulated experience isn't there yet. Either that, or I just don't know all the good places to look. When I have ended up in certain posting areas, it seems like there are many questions asked but not an overabundance of answers. It feels like we're all trying to solve the same problems and we're all running into the same issues.
I will be much happier when I 1) know more, and 2) see more shared knowledge become part of the collective "brain" of the development community.
