I knew I'd read something that touched on all of this so went hunting and found:

Standards For Use Of Technology In Genealogical Research
Recommended by the National Genealogical Society
Remembering always that they are engaged in a quest for truth, family history researchers consistently—
<snip>
•use compilations, communications and published works, whether paper or electronic, primarily for their value as guides to locating the original records.
•state something as a fact only when it is supported by convincing evidence, and identify the evidence when communicating the fact to others.
<snip>
•avoid misleading other researchers by either intentionally or carelessly distributing or publishing inaccurate information.
<snip>
Mindful that computers are tools, genealogists take full responsibility for their work, and therefore they—
<snip>
•treat compiled information from on-line sources or digital data bases like that from other published sources, useful primarily as a guide to locating original records, but not as evidence for a conclusion or assertion.
<snip>
•actively oppose the proliferation of error, rumor and fraud by personally verifying or correcting information, or noting it as unverified, before passing it on to others.

What this means to me is that, FOR ME, it would be wrong to refer others to links if I haven't personally fact-checked the information at that link. And I'm just not going to take on the clean-up of Wiki in addition to all my other projects, so FOR ME, I'm not going to link to a Wiki profile in lieu of writing up the About Me with info I know to be accurate.
