So far, the experience on the crowdfunding has been really positive. In 10 days of funding, there are already 168 funders and 41% of the basic funding goals have been reached!
Also, it was nice to gather feedback and talk to many PyDev users out there.
Regarding PyDev, reactions were pretty positive, but regarding LiClipse, they were initially a bit mixed.
On the dark theme, it was either a love or hate reaction, but just to note, although that's one of the major points of LiClipse, it will definitely not force you to use a dark theme -- it'll be an opt in, not opt out -- and I expect that part to be the easy / fast part in the proposal :)
As for the languages support, initially it was a bit more neutral (with some ups and downs), and I think initially I did a bad job on explaining why I think that was needed, so, I've updated http://igg.me/at/liclipse to explain the 'why' part too :)
Note that as a result of talking to PyDev users, I did change the funding a bit too: there's now a special perk (named PyDev Knight) which empowers users who enjoy PyDev and only really care about a better Python support and not a dark theme or other languages (even if related to Python, such as Django Templates, Mako, etc).
So, I can only thank everyone so far for contributing and spreading the word on the funding!
