Juliapackages and Juliaobserver

Juliahub.com is great, but many pages have links to juliapackages.com or juliaobserver.com, and not been able to see anything could give a very bad impression. If juliahub.com is the replacement, it should be better to redirect the URL.

There are two different services (with their respective histories) involved here:

• Julia Observer and Julia Packages (the ones with the black screen) are open source package browsing tools, with Julia Packages meant to be the replacement of Julia Observer.
• JuliaHub has nothing to do with them (except that also has a package browsing tool): it is a broader service provided by Julia Computing that replaces pkg.julialang.org
