Writing good software is hard and all consuming. Staying motivated day in, day out can be difficult. I applaud people that do this as a hobby, but I can well imagine them getting burnt out. IMO this is also one of the big issues with Open Source Software.
If you use free software you can't expect lots of updates and great support. Heck it is hard enough getting this from commercial software developers (present company excepted)
, who's lively hoods depend on delivering "good" products and supporting them. I know many will say that lots of commercial software is crap and gues what, they are right.
Keynote and PIM users should have a look at Surfulater
. It does a lot more than just save Web content. [/plug]
