I want one communications link, and on that landing page I do expect guidance which channel will serve my needs with which content.
There are Q&A help desks for bidirectional communication, there are newsletters in a one-way mode, some are addressed to MW developers, some are heading for people maintaining a MW installation, some are informing WMF networking and server people, some are for maintaining mediawiki.org content. Some may be a forum, a mailing list, a blog, an IRC, a bug report entry.
I want Tech Blog embedded in this overall picture and when exploring all these channels I want a brief explanation which area is covered, and which audience is addressed.
Tech Blog is mentioned there today, and got such a brief description. Among 28 channels, and this is fine and sufficient.
