A cobweb can be a metaphor for many things. especially the web - the Internet - which has little search engine spiders crawling all over it for new feed..

I watched the BBC David Attenboroughs "Life in the Undergrowth" and he exposed a lot of things about spiders..
some - like the trapdoor, jump out at their prey, others like the Aussie red back make vertical curtain webs to catch insects.

Others make a large single web which they defend against the smaller thief spiders, who come and steal their "catch of the day". The small ones creep across the web, anchor the prey, and cut the lines, and make their escape.

Still others, are more collaborative, and they build masses of cobwebs all connected to each other.
They are small spiders (English ones) BUT their MASSIVE cobweb can catch a small bird and then they have a meal big enough to share. Which they do!
They are a community, much like the internet.
When we collaborate and share, we can achieve much more.
