I'll tell you why you're being downvoted. Compare these two
Your presentation of the problem & solution:
to be +10, but now they're +5. So two users are needed to push them
over as opposed to one earlier (or for answers). To solve this, let's
lower the threshold for new users. Yay?
Our interpretation of your question:
electronics.se are not voting enough. Dude's asking to lower threshold
and make it easier to spam rather than deal with problems in his site. Not cool.
True, on a lot of the bikeshed.se sites, you can ask anything and get 10 upvotes before the mod-hammer is brought out and on some of the more serious sites, upvotes are hard to come by. However, I must agree that it is your community that has a problem here, and the solution is not to fix the engine.
The problems I see here are two fold.
- People aren't editing enough
If a new user cannot include a link or post an image (note that they can't display the images, but they can definitely upload the image and leave up to two image links in their post), then it's up to the community to swing by and edit the links to display the image. The user can always add additional links in the comments, if necessary.
People aren't voting enough
The underlying problem here is that people aren't voting enough. Here's an analogy:
If only 30% of the electorate in a country turn up for the polls, do you think the correct solution is a change in attitude of the society or a lowering of the voting age by an amendment to the laws?
I think that a change in voting behaviour is what's required here. Voter apathy is more harmful in the long run (see webapps.se), and can eventually lead to users getting frustrated at their contributions not being recognized. You should probably raise this issue on your meta site (if possible, with statistics). Link to this blog post if necessary.
Here is a similar post of mine on gardening.se, where I got the data using the API and shared the stats with the community. Voting certainly increased after that (it also happened to coincide with fall season in the northern hemisphere). Although a few users still account for a large number of the votes given out, I do see a lot of new users voting regularly. Here is the voting stats for a three month period since I wrote that post (16 Aug), and you can clearly see the increase*.
TLDR: Mods shouldn't be trying to canvas upvotes for a user regardless of the quality of the post, just so they can add a few links. You should share this voting apathy prevalent in EE with your community, instead of trying to workaround with fixes to the engine.
*For those wondering why the dip in late Sept – early Oct and then a second, smaller peak: the dip is most likely due to people winding up their gardening as the frost sets in the northern hemisphere and the second peak is due to it being spring time in the southern hemisphere.
