These are strange political times, as Sky's Adam Boulton commented from outside Number 10 while Baroness Thatcher enjoyed a two-hour love in with the Browns and Sybil the cat.
Boulton's blog has lots of the gory details, and Nick Robinson says the Brown camp saw the visit as pre-election "psychological warfare".
Was having the Iron Lady for such a public visit a risky move? It certainly caused some problems for Kevin Maguire of Labour's chief cheerleader, the Mirror.
He posts about it with obvious distaste here, and by Friday morning's paper his opposition seemed to have stiffened.
Iain Dale acknowledges Brown's potential to destroy the Conservatives, calling him "the most ruthless prime minister of this country since Francis Urquhart".
The strongest reaction from the right was by Thatcherite MP and former David Davis adviser Robert Wilson, who questioned Brown's moral compass. He wrote on Conservativehome: "She is elderly, she is lonely, she is frail and she has difficulty with her memory... Is it right that a serving prime minister should exploit a situation like this for his own political ends?"
The comments on the site are split between those who agree, and those who think Lady Thatcher was right to give Cameron a bloody nose for straying from the true path.
The visit provoked a hostile reaction from some of the unions, but many Labour bloggers were sanguine. Snowflake5 says "vengeance isn't part of the Labour character", and thinks she set in train the collapse of the Tories - "the least we can do is give her tea".
Chris Paul says she is now "a harmless grannie", while Luke Akehurst is personally "nauseated" but acknowledges the gesture might help win over swing voters.
Dave Hill at Temperama, meanwhile, thinks it represents "moral bankruptcy" - on Baroness Thatcher's part - and blames the media for overplaying a story that was "of no political significance".
Talking of overblown stories, the towering event of the week was of course the announcement that Downing Street has a new cat. Congratulations to MSN News for offering lovers of cats in the corridors of power 15 related pictures. The raw footage is on YouTube here.
Memories of the 1980s have been cropping up for other reasons this week. Cameron gave an interview to the Telegraph's online TV channel, leading the paper - rather optimistically - to predict that an opposition day debate on the EU treaty would be the biggest parliamentary showdown since Maastricht.
Our Kingdom reflects on the similarities between Brown's situation and that of John Major, and wonders if the Tories are now being offered their revenge?
Right and left may be becoming less and less appropriate for describing modern politics, but the Times' Peter Riddell presented some fascinating polling demonstrating the importance of the centre ground.
Without wishing to trivialise politics any further, Comment Central also links to a story suggesting that Jack Straw may have developed a new special relationship with a Croatian minister.
Conferences kick off in earnest this weekend, with several smaller events already under way. Tygerland points out that Political Penguin was blogging from the Co-Operative Party gathering, while for what's happening with the Greens in Liverpool try Derek Wall's blog.
Wall is the snappily-named principal male speaker of the party, and details of the debate over whether to elect a more conventional leader are here.
The Times this week ran a story about attempts to reduce or mitigate the environmental impact of party conferences. Perhaps the most intriguing sentence was: "The Green Party... rejects the principle of carbon offsetting but will offset anyway after the conference."
Plaid is also meeting in Llandudno, and Miserable Old Fart has a well-justified rant about its TV coverage. BBC Parliament - often the victim of hard-to-fathom scheduling - is giving the party an hour a day, choosing instead to run repeats of the TUC conference in Brighton.
The excellent Tiger Tales is there and seems to be blogging.
